Subject [jira] [Commented] (HBASE-16074) ITBLL fails, reports lost big or tiny families
Date Wed, 06 Jul 2016 22:12:11 GMT

    [ https://issues.apache.org/jira/browse/HBASE-16074?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15365221#comment-15365221

stack commented on HBASE-16074:
-------------------------------

Pardon the confusion. There seems to be two issues at this point; one to do w/ TableInputFormat
mangling scan returning non-existent region start rows (non-reproducible in straight scan)
and then a latent dataloss issue that shows rarely. The former seems strongly related to HBASE-15650,
an issue NOT in 1.2. The rare dataloss item may be 1.2 but unproven as yet. [~busbey]

figure it out. Opening this to raise awareness and see if someone saw that recently.
