A trivial fix is to lower the epsilon to 2^-52 or even 2^-53. An option to consider too is just to shift the jitter to always decrement hbase.hregion.max.filesize (MAX_FILESIZE) instead of increase the size of the region and having to deal with the round off. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
