hi Abhilash,

Is this step blocking cube building? (is it crashing your hbase?)​
Checking LZO will try/catch exception, but it does no harm.
If kylin finds out that LZO is not available, it will give up to use LZO
and go on:

[pool-7-thread-10]:[2015-08-06
08:42:26,052][INFO]*[org.apache.kylin.job.hadoop.hbase.CreateHTableJob.run(CreateHTableJob.java:104)]
- hbase will not use lzo to compress data*
2015-08-06 08:42:26,084 INFO  [pool-7-thread-10] compress.CodecPool: Got
brand-new decompressor [.snappy]
2015-08-06 08:42:26,085 INFO  [pool-7-thread-10] compress.CodecPool: Got
brand-new decompressor [.snappy]
