[jira] [Commented] (HBASE-25540) ArrayIndexOutOfBoundsException
thrown when table CF name is "#"
[ https://issues.apache.org/jira/browse/HBASE-25540?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17293333#comment-17293333 ]
Pankaj Kumar commented on HBASE-25540:
--------------------------------------
Thanks [~anoop.hbase] for the pointer.
As discussed offline, currently CF name only can contain # (table & namespace name only support alphanumeric chars). So we can do indexOf(#) and then do substring to parse the store name which will be less CPU intensive compared to Pattern.quote() approach.
Have raised PR, please review.
