chaijunjie resolved HBASE-28150.
--------------------------------
Fix Version/s: 2.6.0
Resolution: Cannot Reproduce
After https://issues.apache.org/jira/browse/HBASE-26454
HMaster will not create tmp table dir, so it will not reproduce，so it just
influence HBase 2.5 and 2.4
close it, use HBase 2.6 is ok
> Too many master region WAL cause HDFS disk space full
> -----------------------------------------------------

> Key: HBASE-28150

> Project: HBase
> Issue Type: Bug
> Affects Versions: 2.4.14
> Reporter: chaijunjie

> Priority: Critical
> Fix For: 2.6.0

>
> create a table, but it failed when execute CREATE_TABLE_WRITE_FS_LAYOUT, then
> will try again and again, will write too many proc record to master:store, we
> find num of the master WAL in oldWALs more than 13000..
>
> Q: should add a suspend time logic for create table proc retry? i see
> TransitRegionStateProcedure has the logic..
