Konstantin Shvachko updated HDFS-7611:
--------------------------------------
Component/s: namenode
Description: If quotas are enabled a combination of operations
*deleteSnapshot* and *delete* of a file can leave orphaned blocks in the
blocksMap on NameNode restart. They are counted as missing on the NameNode, and
can prevent NameNode from coming out of safeMode and could cause memory leak
during startup. (was: I've seen it failing on Jenkins a couple of times.
Somehow the cluster is not comming ready after NN restart.
Not sure if it is truncate specific, as I've seen same behaviour with other
tests that restart the NameNode.)
Priority: Critical (was: Major)
Target Version/s: 2.7.0 (was: 3.0.0)
Affects Version/s: (was: 3.0.0)
2.6.0
Summary: deleteSnapshot and delete of a file can leave orphaned
blocks in the blocksMap on NameNode restart. (was:
TestFileTruncate.testTruncateEditLogLoad times out waiting for Mini HDFS
Cluster to start)
Changed the description. It used to be:
TestFileTruncate.testTruncateEditLogLoad times out waiting for Mini HDFS
Cluster to start.
> deleteSnapshot and delete of a file can leave orphaned blocks in the
