Hi,
I'm using HBase 0.94.5 with thrift server. I'm trying to get the rows from
HBase using
org.apache.hadoop.hbase.thrift.generated.Hbase.Client.getRows(ByteBuffer,
List<ByteBuffer>, Map<ByteBuffer, ByteBuffer>) but it is giving results
very slowly (around 2 mins for 100 rows). For larger number of records,
there is no response.
I've two region server and a total of 128 regions. Total data size is
around 250GB (250 million records) uniformly distributed across regions.
Regionserver only show the following in its log:

Any idea what might be wrong here?
