Both gohbase (https://github.com/tsuna/gohbase) and > AsyncHBase (https://github.com/OpenTSDB/asynchbase) interprets this as > "TableDoesNotExist", which is returned to the client. > Here's a gist that reproduces this problem: > https://gist.github.com/Timoha/c7a236b768be9220e85e53e1ca53bf96. Note that > you have to use older HTable client (I used 1.2.4) as current versions ignore > `Get.setClosestRowBefore(bool)` option. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
