After the split, there were a number of bulk imports interspersed with two user-initiated major compactions that appear to have finished successfully. On the third user-initiated compaction, we failed on an exception similar to the one above. After about 2 minutes to repeated majc failure, the tablet was unloaded and not reloaded anywhere else, so I have to assume that the table was deleted (likely a fair assumption given what the randomwalk was doing). > Major compacting files not empty > -------------------------------- > > Key: ACCUMULO-2082 > URL: https://issues.apache.org/jira/browse/ACCUMULO-2082 > Project: Accumulo > Issue Type: Bug > Reporter: Josh Elser > > Saw this during a randomwalk: > {noformat} > MajC Failed, message = Major compacting files not empty [hdfs://nameservice/accumulo/tables/p/t-0001pfx/C0001qir.rf, hdfs://nameservice/accumulo/tables/p/t-0001pfx/C0001qip.rf, hdfs://nameservice/accumulo/tables/p/b-0001qh4/I0001qh5.rf, hdfs://nameservice/accumulo/tables/p/b-0001qgt/I0001qgv.rf, hdfs://nameservice/accumulo/tables/p/b-0001qg5/I0001qg6.rf, hdfs://nameservice/accumulo/tables/p/b-0001qem/I0001qeo.rf, hdfs://nameservice/accumulo/tables/p/b-0001qgj/I0001qgk.rf, hdfs://nameservice/accumulo/tables/p/t-0001pfx/C0001qis.rf, hdfs://nameservice/accumulo/tables/p/b-0001qga/I0001qgb.rf, hdfs://nameservice/accumulo/tables/p/t-0001pfx/A0001pg9.rf] > java.lang.IllegalStateException: Major compacting files not empty [hdfs://nameservice/accumulo/tables/p/t-0001pfx/C0001qir.rf, hdfs://nameservice/accumulo/tables/p/t-0001pfx/C0001qip.rf, hdfs://nameservice/accumulo/tables/p/b-0001qh4/I0001qh5.rf, hdfs://nameservice/accumulo/tables/p/b-0001qgt/I0001qgv.rf, hdfs://nameservice/accumulo/tables/p/b-0001qg5/I0001qg6.rf, hdfs://nameservice/accumulo/tables/p/b-0001qem/I0001qeo.rf, hdfs://nameservice/accumulo/tables/p/b-0001qgj/I0001qgk.rf, hdfs://nameservice/accumulo/tables/p/t-0001pfx/C0001qis.rf, hdfs://nameservice/accumulo/tables/p/b-0001qga/I0001qgb.rf, hdfs://nameservice/accumulo/tables/p/t-0001pfx/A0001pg9.rf] > at org.apache.accumulo.tserver.Tablet$DatafileManager.reserveMajorCompactingFiles(Tablet.java:933) > at org.apache.accumulo.tserver.Tablet._majorCompact(Tablet.java:3187) > at org.apache.accumulo.tserver.Tablet.majorCompact(Tablet.java:3371) > at org.apache.accumulo.tserver.Tablet.access$4700(Tablet.java:168) > at org.apache.accumulo.tserver.Tablet$CompactionRunner.run(Tablet.java:2849) > at org.apache.accumulo.trace.instrument.TraceRunnable.run(TraceRunnable.java:47) > at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1145) > at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:615) > at org.apache.accumulo.trace.instrument.TraceRunnable.run(TraceRunnable.java:47) > at org.apache.accumulo.core.util.LoggingRunnable.run(LoggingRunnable.java:34) > at java.lang.Thread.run(Thread.java:744) > {noformat} > I don't actually know if it's a problem.
