------------------------------------------
Summary: Limit the number of Snapshots allowed to be created for a
Snapshottable Directory
Key: HDFS-12947
URL: https://issues.apache.org/jira/browse/HDFS-12947
Project: Hadoop HDFS
Issue Type: Improvement
Reporter: Shashikant Banerjee
Assignee: Shashikant Banerjee
Currently, A snapshottable directory is able to accommodate 65,536 snapshots.
In case a directory has large no of snapshots , deletion of any of the earlier
snapshots take a lot of time which might lead to namenode crash (HDFS-11225).
This jira is introduced to limit the no of the snapshots under a snapshottable
directory to a reasonable value(say 10) which can be overriden.
