Hello HBase Users,

 

I'm running HBase 0.20.6 in a clustered environment containing 2 region
server and 1 master in a fully distributed mode.

Even the components zookeeper is a quorum of 3 and HDFS as 1 name
node/secondary name node and 2 data nodes.

 

I'm using HBase client to creating a table and inserting data, and if I
query the same table, I get exception TableNotFound.

 

While the base scanner triggers I see the debug message "Current assignment
of  testTable,,123456789 is not valid ; server address:<Region Server IP>,
startcode:1987877776 unknown" followed by "Assigning region
testTable,,123456789 to linux.site.temp,60020,55678899" and hence it again
reassigns back to the same server and hence it continues.

 

>From HBASE shell in that particular Region Server , I could able to scan the
table, no issues then.

 

But while the base scanner sleeps, as sleep time configured, I could able to
query the table data, no exception comes then.

So it sometimes occur, sometimes not.

 

Kindly provide me your inputs. What to do.

-Mohit
