Subject Cannot find row in .META. for table
Date Tue, 11 Mar 2014 11:25:47 GMT

Hi,
I am using Hbase 0.94.1 with Hadoop 1.2.1 and using Thrift API to access tables stored in
Hbase from my C# application. I am able to connect to Server but while going to perform any
operation from client it gives following error in CLI-log:

14/03/11 12:18:53 WARN client.HConnectionManager$HConnectionImplementation: Encountered problems
when prefetch META table:
org.apache.hadoop.hbase.TableNotFoundException: Cannot find row in .META. for table: tblAssetsView,
row=t\x00\x00\x00b\x00\x00\x00l\x00\x00\x00A\x00\x00\x00s\x00\x00\x00s\x00\x00\x00e\x00\x00\x00t\x00\x00\x00s\x00\x00\x00V\x00\x00\x00i\x00\x00\x00e\x00\x00\x00w\x00\x00\x00,,99999999999999

But I can access my table from Hbase Shell with all shell operations. I am totally stuck here,
please devise some methods to overcome this issue.
