QUESTION
DSE server Version : 6.8 Followed installation steps as per the datastax documentation (Tar file installation)
Startup command: bin/dse cassandra -s (Needs search featire , so enabled solr as well)
Error while executing start command:
...ANSWER
Answered 2022-Mar-01 at 22:38The error is most likely a symptom of another problem. For example, it's quite common to get "class not found" exceptions when using Java 11 with Cassandra. DataStax Enterprise 6.8 is compatible with Cassandra 3.11 which only supports Java 8.
For what it's worth, Java 11 support was only added to Cassandra 4.0 (CASSANDRA-16894). Older versions of Cassandra only work with Java 8.
Going back to your original question, we need a bit more information to investigate the issue but our ability to help you in a Q&A forum is limited. Please log a ticket with DataStax Support and one of our engineers will advise you on what diagnostic info is required and the next steps. Cheers!

I was trying to remove the log4j dependency from my project which is a huge repository. After having a close look in gradle files I found one of the module refers to the log4j dependency, which I excluded in gradle as shown in below code - exclude group: 'log4j', module: 'log4j'
...ANSWER
Answered 2022-Jan-19 at 22:42I would use below but also make sure you add the correct slf4j library to replace the interface ie. log4j-over-slf4j
QUESTION
This is the result of my BDP CALL
bdp("AU3FN0051587 Corp", 'YAS_OAS_SPRD')
arguments
isin=AU3FN0051587 Corp
field=YAS_OAS_SPRD
Result
.000
The answer is not equals to the value in the terminal. Is there a reason?
Thank you
...ANSWER
Answered 2021-Nov-11 at 20:39I ask to bloomberg.
Unfortunately, rules on AU3FN0051587 block it in Data License hence you don't get any value returned for YAS_OAS_SPRD. Same rules allow CA31430WAB06 and hence correct value is returned. The rule is recognized by a field in FLDS -> CALC_TYP.
QUESTION
I have stargate 1.0.38 running fine in my DEV server. I am able to use stargate rest api to get auth_token and running insert, select queries.
Yesterday, I have created an index Cql3SolrSecondaryIndex for a table in my Cassandra DSE 6.8. Then I see bellow error in stargate log. After that, I dropped that index. But even after dropping the index, i still see bellow error in stargate log. I also try to stop/start stargate but the still see same error.
...ANSWER
Answered 2021-Oct-15 at 02:57Stargate does not currently support advanced workloads like Search and Graph. I think you might have to drop and recreate that keyspace without the Solr index for it to work again since the schema still exists on the other nodes.
This issue has been documented here. There has also been a request made to support Solr here.
QUESTION
I've found numerous answers relating to .NET Core 3.1 and .NET 5.0 on Windows, but so far have been unable to find how to get the original assembly location under .NET Core on Linux when using a single-file executable. Given that the systems behave differently, I think this is probably a bug in .NET 5, but I need a workaround in the mean time. Note that in my scenario, the current directory is not where the original executable is located, even if I don't change it, and I have no control over it (and that's a hack anyway--the purpose of current directory is completely different). Here's the actual output of a test program under this scenario with the properties and functions that have been suggested in all the other posts I've been able to find so far:
...ANSWER
Answered 2021-Oct-17 at 20:21When you publish your app as single executable file, some APIs related to Assembly will not work, and this is not a bug.
It is documented here: https://docs.microsoft.com/en-us/dotnet/core/deploying/single-file#api-incompatibility
There you'll see in that table that Assembly.Location
will always return empty string when running in a single executable file.
As suggested in that doc, you could call Environment.GetCommandLineArgs()
and evaluate the value of the first item in the string array result.

I have installed Cassandra on Kubernetes (9 pods) All the pods are up and running except for one pod, which shows the below error.

Answered 2021-Sep-06 at 06:57For whatever reason, one of the commit log segments got corrupted on the node.
You can workaround the issue by manually deleting this file on the pod:
QUESTION
Is there a way to use the BQL-formula in Python in the BLPAPI or XBBG API's instead of looping through a bunch of tickers to retrieve data on i.e. all of the stocks of the S&P500 using a BDP or BDS formula? (This will quickly reach the data limit for the day, I suspect, since I want to check a bunch of different indicies).
I found a post from 2019, where BQNT was suggested, but I would prefere to avoid using BQNT, link here: How to implement BQL Bloomberg excel formula to python API (blpapi)?.
Thanks in advance!
...ANSWER
Answered 2021-Sep-01 at 13:14Further to the comments, I played around with a proof-of-concept for driving Excel from Python. This quick'n'dirty script opens Excel in the background, puts a BQL formula in a cell, polls for a return value, and fills a DataFrame:
QUESTION
I'm on my research project to find the last price for a security at IPO and 20 trading days after for 5 years. I use =BDP($A$1, "EQY_INIT_PO_DT") to get the IPO trading date and its fine. The issue happened when I use =BADDPERIODS(A2, "NumberOfPeriods", "20", "CDR", "ID JA", "BusDayAdj", "1") it still include the non trading days. So when I use =BDH($A$1, "PX_LAST", A6, A6) it shows #N/A N/A. I guess =baddperiods() function outputted the non trading days and the =bdh() unable to get the price. How can I obtain the correct 20 trading days (exclude weekends and any public / non-trading days) after a certain date?
...ANSWER
Answered 2021-May-24 at 18:03The BDH() worksheet function has optional parameters that specify how the timeseries data is returned. These come after the start and end date parameters. One of these allows a calendar to be specified. Specifying a calendar prompts Bloomberg to look back and find the closest (but earlier) 'good' value for the date requested.
The short, but inefficient answer is to use this formula in cell B6:
QUESTION
I am trying to run compile below function in scala
...ANSWER
Answered 2021-Mar-12 at 05:17You're using the dot-less instance method arg syntax without the arg. The compiler goes looking for the arg and finds the (intResult,stringResult)
tuple and tries to pass that to the !!
method, which doesn't work.
Use cmd.!
and cmd.!!
instead.
Also: If you use a ProcessLogger
then you can capture the exit code (Int
), as well as StdOut and StdErr (String
s), with a single execution of cmd
instead of invoking it twice, as you are doing now.
