Robert Joseph Evans created HDFS-3973:
-----------------------------------------
Summary: Old trash directories are never deleted on upgrade from
1.x
Key: HDFS-3973
URL: https://issues.apache.org/jira/browse/HDFS-3973
Project: Hadoop HDFS
Issue Type: Bug
Affects Versions: 0.23.3, 2.0.2-alpha
Reporter: Robert Joseph Evans
The older format of the trash checkpoint for 1.x is yyMMddHHmm the new format
is yyMMddHHmmss(-\d+)? so if you upgrade from an old cluster to a new one, all
of the entires in .trash will never be deleted because they currently are
always ignored on deletion.
We should support deleting the older format as well.
