[jira] [Commented] (HBASE-6924) HBase Master spews into a loop if a
user attempts to create a snappy table when snappy isn't properly
configured
[ https://issues.apache.org/jira/browse/HBASE-6924?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13468012#comment-13468012 ]
Alex Newman commented on HBASE-6924:
------------------------------------
I assume the issue is that opening a region can often fail and we want some retry logic.
