Hello here,
I have a question regarding HBase data locality in respect to HDFS data nodes.
As far as I understand regions created by region servers will happen to be
physically created on local Data Node if RegionServer happen to run on one.
I had an issue with writing to Meta table and my table "dissapeared" from list
of tables. After I restarted hbase everything went back to normal, but regions
got reassigned to different region servers they were originally created.
How this "(re)assignment" mechanism actually works?
I am using hbase 0.20.4 at the moment.
Thanks
