[jira] [Comment Edited] (HBASE-7651) RegionServerSnapshotManager
fails with CancellationException if previous snapshot fails in per region
task
[ https://issues.apache.org/jira/browse/HBASE-7651?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13562107#comment-13562107 ]

-----------------------------------------------------------------
pe-snapshots.sh was the line right below it:
{code}
echo "(1..$SSCOUNT).map {|x| snapshot 'TestTable', 'pe-'+x.to_s}" | hbase shell
{code}
list_snapshots lists the names of the snapshots that matche the regex -- so we try to take SSCOUNT=30 snapshots call pe-1, pe-2...pe-30, and then list all that match pe-*. This fails only if there are not snapshots. In the logs we'd see the first log from the description and then all others would fail with essentially the second log in the description.
