[jira] [Created] (MAPREDUCE-4137) MRAppMaster shutdown hook should
not call FileSystem.closeAll()
MRAppMaster shutdown hook should not call FileSystem.closeAll()
---------------------------------------------------------------
Key: MAPREDUCE-4137
URL: https://issues.apache.org/jira/browse/MAPREDUCE-4137
Project: Hadoop Map/Reduce
Issue Type: Bug
Components: mrv2
Affects Versions: 2.0.0
Reporter: Alejandro Abdelnur
Fix For: 2.0.0
Filesystem.closeAll() attempts to remove the FileSystem shutdown hook.
This triggers an exception
{code}
Exception in thread "Thread-1" java.lang.IllegalStateException: Shutdown in progress
at java.lang.ApplicationShutdownHooks.remove(ApplicationShutdownHooks.java:55)
at java.lang.Runtime.removeShutdownHook(Runtime.java:220)
at org.apache.hadoop.fs.FileSystem$Cache.remove(FileSystem.java:2101)
at org.apache.hadoop.fs.FileSystem$Cache.closeAll(FileSystem.java:2133)
at org.apache.hadoop.fs.FileSystem$Cache.closeAll(FileSystem.java:2110)
at org.apache.hadoop.fs.FileSystem.closeAll(FileSystem.java:361)
at org.apache.hadoop.mapreduce.v2.app.MRAppMaster$MRAppMasterShutdownHook.run(MRAppMaster.java:1013)
{code}
Besides, because the FileSystem has its own shutdown hook that does a closeAll() the call from MRAppMaster is not needed.
