Client Scanner mechanism that is used for HbaseAdmin methods (listTables,
tableExists), is very slow if the client is far away from the HBase cluster
-----------------------------------------------------------------------------------------------------------------------------------------------------
Key: HBASE-1874
URL: https://issues.apache.org/jira/browse/HBASE-1874
Project: Hadoop HBase
Issue Type: Improvement
Affects Versions: 0.20.0
Reporter: Andrei Dragomir
Priority: Minor
I have a simple class that instantiates an HBaseAdmin object, and tries to
connect to a remote hbase cluster (latency about 300ms).
When doing any kind of simple operation, like listTables, tableExists, it takes
a huge amount of time, because the mechanism is to instantiate a scanner on the
client, so for each row in the .META. table, we get a client - cluster
roundtrip. This is prohibitive in the case of a far away client.
