Hi,
I am trying to install snappy compression for HBase. I believe I have
installed the library and wanted to check by using the CompressionTest
utility. I am issuing the following command:
bin/hbase org.apache.hadoop.hbase.util.CompressionTest
hdfs://C-Master:/usr/local/hadoop/hbase snappy
However, when I run the command I get the following output:
13/11/27 14:29:20 INFO ipc.Client: Retrying connect to server:

My HBase cluster is running without issue, so I am puzzled as to why the
test utility is having difficulty connecting to the master node
(particularly since I was running the test on the master node itself). Have
I missed something/used improper syntax/etc?
Any help would be greatly appreciated.
Thank you.
