Re: How to install Snappy?
Hi,

Something more about my workaround last time:

I used the following steps to test my workaround:  

1) cd $HBASE_HOME
./bin/hbase org.apache.hadoop.hbase.util.CompressionTest file:///tmp/testfile lzo
2) hbase shell
create 't1', {NAME => 'cf1', COMPRESSION => 'LZO'}
You could modify above for your test cases.

Good luck
Thanks
AC
