QUESTION
EDIT: Although yukim's workaround does work, I found that by downgrading to JDK 8u251 vs 8u261, the sigar lib works correctly.
- Windows 10 x64 Pro
- Cassandra 3.11.7
NOTE: I have JDK 11.0.7 as my main JDK, so I override JAVA_HOME and PATH in the batch file for Cassandra.
Opened admin prompt and...
java -version
...ANSWER
Answered 2020-Jul-29 at 01:05I think it is sigar-lib that cassandra uses that is causing the problem (especially on the recent JDK8).
It is not necessary to run cassandra, so you can comment out this line from cassandra-env.ps1 in conf directory: https://github.com/apache/cassandra/blob/cassandra-3.11.7/conf/cassandra-env.ps1#L357
QUESTION
When running npm install
to download project dependencies, sqlite3
encounters an error and never installs. Trying npm install sqlite3
produces same error.
Running on Linux Beta (Debian v10 buster) on ChromeOS.
Installs fine on others' machines. Expect it has something to do with ChromeOS.

can't download a prebuilt binary and thus falls back to building it with node-gyp
. This is where the build fails.
Note the line in your log where it says: gyp ERR! stack Error: not found: make
It seems as if you don't have make
installed. Since you're on Debian, you should be able to install make
by running: sudo apt-get install build-essential
.
This question has already been extensively discussed in the following question: npm failed to install time with make not found error
Make sure to take a close look at error messages :)
QUESTION
I've build a new cluster with cassandra 3.11.3, filled it with data from old cluster with cassandra 2.0.14 and few hours after switching application to this new cluster I've got memory errors:
...ANSWER
Answered 2019-May-14 at 21:125gb heaps (-Xmx5120M
) are lower than the minimum recommended heap size of 8gb. While you can probably tune it to make it work the database is not designed with its defaults to run in that limited of a heap. Probably the fastest and most likely way to help is to set concurrent_reads
and concurrent_writes
to 8 or 4. Then concurrent_compactors
and concurrent_validations
(if more recent version) to 1.
If you set the -XX:+HeapDumpOnOutOfMemoryError
and -XX:HeapDumpPath=/somewhere/writable
then on the OOM it will dump the heap and you can open it up and see what is cause. If you get it you can post heap histogram (using jmap on the dump) and people may be able to give more direction - but it may require actually poking around with a tool like yourkit or MAT to know exact cause.
If thats a deadend you can use async profiler
QUESTION
So I've been working on a school project, and this one function has been giving me a lot of trouble. It takes an object in a dictionary from index (x, y), and moves it to a new index. I'm getting a RuntimeError every time I run it, and I assume it's because I'm adding a new index to the dictionary, but I don't know how to solve the problem. An enemy in the enemydict has the 'leap' attribute (an integer) and is at index (xlocation, ylocation). Heres the code;
...ANSWER
Answered 2018-Feb-05 at 21:43The error message means just what it says: you have changed the size of a dictionary while iterating over it.
That happens in this line:
