Accumulo keeps crashing with error

cspencer — Tue, 29 Mar 2016 21:56:05 GMT

The thrift server stops responding and Accumulo crashes. The log shows a lot of these error messages but doesn't really point to what the issue is. Anyone familiar with this?

ERROR: Error occurred during processing of message. java.lang.RuntimeException: org.apache.thrift.transport.TTransportException at org.apache.thrift.transport.TSaslServerTransport$Factory.getTransport(TSaslServerTransport.java:219) at org.apache.accumulo.core.rpc.UGIAssumingTransportFactory$1.run(UGIAssumingTransportFactory.java:51) at org.apache.accumulo.core.rpc.UGIAssumingTransportFactory$1.run(UGIAssumingTransportFactory.java:48) at java.security.AccessController.doPrivileged(Native Method) at javax.security.auth.Subject.doAs(Subject.java:360) at org.apache.hadoop.security.UserGroupInformation.doAs(UserGroupInformation.java:1637) at org.apache.accumulo.core.rpc.UGIAssumingTransportFactory.getTransport(UGIAssumingTransportFactory.java:48) at org.apache.thrift.server.TThreadPoolServer$WorkerProcess.run(TThreadPoolServer.java:208) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1142) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617) at org.apache.accumulo.fate.util.LoggingRunnable.run(LoggingRunnable.java:35) at java.lang.Thread.run(Thread.java:745) Caused by: org.apache.thrift.transport.TTransportException

That exception isn't a direct cause of the server failing -- it's just saying that an RPC failed (it should be suppressed and not logged out). By "thrift server" do you mean TabletServer?

If so, also check the .out/.err files for the process. There may have been some out of memory issue didn't get printed to the log4j file.

@Artem Ervits

is there any timeline when this bug https://issues.apache.org/jira/browse/ACCUMULO-4059 will be fixed? we are also seeing same error (Tservers getting crashed often)

@AR

Like I said in my other comment, this exception does not cause the tabletserver to fail. Please collect all logs and .out/.err for the tabletserver after a failure *but before* restarting the process.

22 days back below errors got logged on all TServers and after 22 days Tservers all went down

Re: Accumulo keeps crashing with error

Great, that's a very helpful message. The Accumulo Master asked this tabletserver to stop. This happens for one of two reasons:

1. The "hold time" for this server (the amount of time that mutations are being held because of a flush/minor-compaction that is in progress) exceeds a given threshold. By default, this value is 5minutes and is defined by tserver.hold.time.max in accumulo-site.xml

2. The Master periodically asks every tabletserver for a status report. If the Master fails to receive a status report from a TabletServer 3 times in a row, it will request that it shuts down (as it implies that the tabletserver is in a bad state).

Both of these cases will result in a log message written to the Master log file. Please check the Master log file shortly before 2016-03-09 20:35:36,971 to understand which reason it was.

@Josh Elser

is this related to bug https://issues.apache.org/jira/browse/ACCUMULO-4069 ?

This is pulled from another environment where we have same issue.

Looks like master was unable to receive tablet status report from T server for 3 times,before that it fails to find any Kerberos ticket

from Tserver:

Yes, seeing "[Caused by GSSException: No valid credentials provided (Mechanism level: Failed to find any Kerberos tgt)]" errors in a sevice after it has been running for some time implies that the issue is ACCUMULO-4069
