If regions assignment fails, clients will be directed to stale data from .META.
-------------------------------------------------------------------------------
Key: HBASE-3660
URL: https://issues.apache.org/jira/browse/HBASE-3660
Project: HBase
Issue Type: Bug
Components: master, regionserver
Affects Versions: 0.90.1
Reporter: Cosmin Lehene
Fix For: 0.90.2
I've noticed this when the IP on my machine changed (it's even easier to detect
when LZO doesn't work)
Master loads .META. successfully and then starts assigning regions.
However LZO doesn't work so HRegionServer can't open the regions.
A client attempts to get data from a table so it reads the location from .META.
but goes to a totally different server (the old value in .META.)
This could happen without the LZO story too.
