CDH5.7.1 The hbase-prefix-tree module jar containing PrefixTreeCodec is not present warning

Hi. 

 

We get this warning after a upgrade to CDH5.7.1. 

 

"WARN [main] mapreduce.TableMapReduceUtil: The hbase-prefix-tree module jar containing PrefixTreeCodec is not present. Continuing without it."

 

Have tried to copy all <parcel>/jars/hbase-* to the folder configured in hive for the "Hive Auxiliary JARs Directory" setting in CMS.

This is a harmless warning currently produced due to HBASE-15152, which will be addressed in a future release.

Re: CDH5.7.1 The hbase-prefix-tree module jar containing PrefixTreeCodec is not present warning

This is an issue in the following case:

 

in a Unix script

 

RET_VALUE=$(hive -e 'select single_row_single_value from table' -S)

 

using -S should suppress all messages (except maybe errors).  This message is not suppressed using -S, which will cause the above case to fail when RET_VALUE is used later on in the script.

Sorry, I don't have my notes from this. We tried 2 things to fix this, one was a brute force add a dummy class to the jar, but that wouldn't work for upgrades. I don't remember what the actual fix was. Cloudera should know, as it was their person who, working with Cloudera support, implemented the correct fix.
