I'm using NiFi 1.23.2 in our production environment. It works fine when TLS is disabled, but after enabling TLS, we encounter a 'too many open files' issue. Through further investigation using lsof combined with the ss command, we discovered a large number of closed TCP connections with socket transmission buffers showing as 0t0. Why does this situation occur? Is this a bug in NiFi itself?

I think I've found the reason for the problem. It's not related to the Spark version. I used the Java process analysis tool Arthas to investigate and found that the AM startup process was blocked at the creation of the Timeline client. And this problem might be due to our TimeLine service using an embedded HBase service. When we configured the HBase used by the TimeLine service to our production environment's HBase, the problem disappeared.

Hi everyone, our Hadoop cluster has recently encountered a strange issue. After starting the cluster, Spark jobs run normally, but after running for more than a week, job submission timeouts occur. Specifically, the jobs are all in the ACCEPTED state, but fail due to timeout after 2 minutes. The error log shows: Caused by: java.net.SocketTimeoutException: 60000 millis timeout while waiting for channel to be ready for read. ch : java.nio.channels.SocketChannel[connected local=/134.1.1.3:45866 remote=hdp144019.bigdata.com/134.1.1.19:45454] I found an app id, and then went to check the corresponding NodeManager log for attempting to start the AM. I found that the AM was never started at all. At the time when the job submission timed out, the NodeManager log reported the following log: 2024-03-15 00:04:17,668 INFO containermanager.ContainerManagerImpl (ContainerManagerImpl.java:handle(1607)) - couldn't find application application_1709910180593_38018 while processing FINISH_APPS event. The ResourceManager allocated resources for this application to the NodeManager but no active containers were found to process. 同时伴随着IPC相关的报错： 2024-03-15 00:04:17,082 WARN ipc.Server (Server.java:processResponse(1523)) - IPC Server handler 11 on 45454, call Call#31 Retry#0 org.apache.hadoop.yarn.api.ContainerManagementProtocolPB.startContainers from 134.1.1.8:32766: output error

Thank you very much for your answer. I will try to adjust the allocation of heap memory. In addition, I would like to ask how the conclusion of using 1GB of memory for every 1 million blocks was drawn? Or is there a more precise calculation method that can lead to such a conclusion?

Hi, I have a Hadoop 3.1.1 cluster and recently I found that the NameNode heap memory usage in the cluster is very high. I saw 629973631 file objects in the cluster through WebUi, so according to my calculations, it should occupy no more than 90GB of memory, right? Why is the current memory usage consistently above 140GB? Is this related to me enabling erasure codes?

I think your intention is to retrieve these data for your own monitoring or reporting tasks. If so, you can try requesting JMX to obtain the relevant data, such as through http://namenode:port/jmx.
