Description

extraRegionsInMeta will not clean/fix meta if info:regioninfo columns is missing.

 

Somehow, the customer has the following empty row in meta as a stale. 
'I1xxxxxx,16332508xxxxx.xxxxf53609cc1ae366b43205dxxxxxxx', 'info:state', 163333223xxxx
 

And no corresponding table "I1xxxxxx" exist. 

 

We use extraRegionsInMeta but it didn't clean. Also, we created same table again and used extraRegionsInMeta after removing HDFS data but the stale row never cleaned. It looks extraRegionsInMeta works only when "info:regioninfo" is present. 

 

We need to handle the scenario for other columns I.e info:state, info:server, etc
