[jira] [Commented] (HBASE-23742) Mob Data, threshold crossed data is considering as normal data.

    [ https://issues.apache.org/jira/browse/HBASE-23742?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17024447#comment-17024447 ] 

Sean Busbey commented on HBASE-23742:
-------------------------------------

I'm not sure how bad this is. On the next compaction we'll pick up that the data should be mob and move it over. It's analogous to how bulk loaded data gets dealt with on a mob enabled cf.

>             Project: HBase
>          Issue Type: Sub-task
>          Components: MTTR
>    Affects Versions: 3.0.0, 2.3.0
>            Reporter: Y. SREENIVASULU REDDY
>            Priority: Major

> Steps to reproduce this issue.
> 1. create a table with 1 region, and mob enabled, keep threshold value to 5.
> 2. Load data into the table, keep the value size should be  more than 5.
> 3. flush the table.
> 4. observe the mobdir and data dir, hfiles should be there.
> 5. load data again with different data set, keep the value size is greater than 5.
> 6. Kill -9 RS where table region is online
> 7. Start RS
> check the mob dir and data dir, both should have 2 hfiles each.
> But data dir only have 2 hfiles, that means mob threshold crossed data is considered as normal data.
