@Shashank and @shamik,   As each person's setup is typically different I was suggesting you start a new thread or conversation. In this new thread you can explain your unique situation in terms of overall system specifications (RAM, number of processors, etc.) as well as how much of those resources have been allocated to the Quickstart VM.   As @jmartin1938 has pointed out the Quickstart VM in inherently slow due to being a single node cluster. The issue can be made worse if the VM is not allcated the appropriate resources or used for large scale projects.    To start a new thread go to the appropriate board and use the "new message" button.    This will open a page for you to post the wording and title for the new thread.  ...

I received a similar error, but for the LzopCodec (not LzoCodec) not being found.  In this case, I actually wanted to use the LzoCodec as my default compression codec (for legacy reasons...).   In order to get Hive working with Lzo on CDH 5.14.x, I did the following:   1) # Add GPLEXTRAS parcel to CM and distribute to all nodes: https://www.cloudera.com/documentation/enterprise/5-14-x/topics/cm_ig_install_gpl_extras.html 2) # Configure HDFS to use it: http://www.roggr.com/2014/06/enabling-lzo-compression-for-hive-to.html ClouderaManager -> Hive -> Configuration -> Service-wide -> Advanced -> Hive Auxiliary JARs Directory : /opt/cloudera/parcels/GPLEXTRAS/lib/hadoop/lib # Verify it works by invoking 'show tables' in hive with debug-logging enabled. There should not be any errors. The error condition if not working complains about LzopCode (not LzoCodec) not found. hive --hiveconf hive.root.logger=DEBUG,console 3) # Configure HDFS ClouderaManager -> HDFS -> Configuration -> Service-wide -> Compression Codes (io.compression.codecs): + com.hadoop.compression.lzo.LzoCodec + com.hadoop.compression.lzo.LzopCodec 4) # Configure YARN/MR2 # http://blog.cloudera.com/blog/2013/07/one-engineers-experience-with-parcel/ ClouderaManager -> YARN/MR2 -> Configuration -> SearchFor: compress -> mapreduce.output.fileoutputformat.compress: checked mapreduce.output.fileoutputformat.compress.codec: com.hadoop.compression.lzo.LzoCodec mapreduce.map.output.compress: checked mapreduce.map.output.compress.codec: com.hadoop.compression.lzo.LzoCodec   ...
