I am making a website. I have a problem now. This is my website right now. As you can see the blue logo in the middle must be against the top. Does anyone know how I can get it against the top? Does that has to do with the flex-box? If that's the case can I get some explanation about the flexbox? Thanks in advance!

The problem is that #mainbox takes the whole width and .nav goes down. One solution would be to make .nav position absolute and top 0.

You have to declare your cube variable outside of createCube(). It's then in a scope that can be accessed by removeCube().

Flink Scala Job Runtime Error : java.lang.NoSuchMethodError

Asked 2020-Oct-23 at 16:28

I am trying to run a simple flink streaming job on AWS EMR. The purpose is very simple for now:

Consume data from Kafka in flink
Load to another topic in kafka.

I am using the following dependencies:

If you're using EMR's Flink support, then most Flink libraries should be flagged as "provided" so that they're not in your jar, as they're on the classpath from the Flink installation that EMR is providing. You'll still need to explicitly include anything that's not provided by EMR (e.g. flink-connector-kafka).

QUESTION

Flink job with CassandrSink fails with Error writing

Asked 2020-Oct-22 at 14:40

I have two simple Flink streaming jobs that read from Kafka do some transformations and put the result into a Cassandra Sink. They read from different Kafka topics and save into different Cassandra tables.

When I run any one of the two jobs alone everything works fine. Checkpoints are triggered and completed and data is saved to Cassandra.

But when ever I run both jobs (or one of them twice) the second job fails at start up with this exception: com.datastax.driver.core.exceptions.NoHostAvailableException: All host(s) tried for query failed (tried: localhost/127.0.0.1:9042 (com.datastax.driver.core.exceptions.TransportException: [localhost/127.0.0.1] Error writing)).

I could not find much info about this error, it may be caused by any one of the following:

Flink (v 1.10.0-scala_2.12),
Flink Cassandra Connector (flink-connector-cassandra_2.11:jar:1.10.2, also tried with flink-connector-cassandra_2.12:jar:1.10.0),
Datastax underlying driver (v 3.10.2),
Cassandra v4.0 (same with v3.0),
Netty transport (v 4.1.51.Final).

I also use packages that may have collisions with the first ones:

mysql-connector-java (v 8.0.19),
cassandra-driver-extras (v 3.10.2)

Finally this is my code for the cluster builder:

I might be wrong, but most likely the issue is caused by netty client version conflict. The error states NoHostAvailableException, however the underlying error is TransportException with Error writing error message. Cassandra s definetely operating well.

There is a kind of similar stackoverflow case - Cassandra - error writing, with a very similar symptoms - a single project running well and AllNodesFailedException with TransportException with Error writing message as a root cause when adding one more. The author was able to solve it by unifying the netty client.

In your case, I'm not sure why there are so many dependencies, so I would try to get rid of all extras and libraries and would just leave Flink (v 1.10.0-scala_2.12) and Flink Cassandra Connector (flink-connector-cassandra_2.12:jar:1.10.0) libraries. They must already include necessary drivers, netty, etc. All other drivers should be skipped (at least for initial iteration to ensure that this solves the issue and it's library conflict).

From the stacktrace above, com.datastax.driver.core.exceptions.NoHostAvailableException: All host(s) tried for query failed (tried: localhost/127.0.0.1:9042 it seems that the cassandra hosts are not available.

I would say you need to expose the ports to outside :

QUESTION

What does it mean when you get "too many open files" on the Kafka Consumer/Client?

Asked 2020-Feb-20 at 22:25

I know that this usually means the ulimit needs to be increased. But what does this actually mean when it happens on the consumer side?

I'm using Apache Flink and I got this error on my Flink task node. When I reboot my Flink node and redeployed the job it worked fine. The brokers also seemed fine at the time.

I have a total of 9 tasks running over 3 nodes. Max parallelism for any one job is 1 to 2. So lets assume worst case 18 parallelism/threads over 3 nodes.

...

ANSWER

Answered 2020-Feb-20 at 20:06

Every Kafka client (producer, consumer) maintains a single socket per every broker in the cluster its connected to (worst case).

so youre looking at number of clients flink creates times number of brokers in your cluster

sockets count as handles for purposes of ulimit.

I dont know how many kafka clients flink creates internally - you could grab a heap dump and see how many client objects are in there
