Subject [jira] [Commented] (HBASE-18030) Negative tag length for hbase block/hfile
Date Thu, 11 May 2017 09:48:04 GMT

    [ https://issues.apache.org/jira/browse/HBASE-18030?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16006165#comment-16006165

ramkrishna.s.vasudevan commented on HBASE-18030:

In that case you are using Tag feature of hbase. Internally per cell TTL is implemented as
Tags. Ok will now look into the code to understand what could be possibly wrong and come back
If possible try to replicate your use case with a simple test case with per Cell TTL.
