Shivram Mani commented on HAWQ-1427:
------------------------------------
This class is available as part of hive-exec jar which is configured as a run
time dependancy in pxf-private.classapth. On clusters which don't have hive
rpms this issue would occur.
Will switch to using the preexisting org.apache.commons.lang utility instead.

> Key: HAWQ-1427
> URL: https://issues.apache.org/jira/browse/HAWQ-1427
> Project: Apache HAWQ
> Issue Type: Bug
> Components: PXF
> Reporter: Shivram Mani
> Assignee: Shivram Mani

> Issue with querying JSON data with PXF
> Getting the following error
> ```
> ERROR: remote component error (500) from '10.101.170.74:51200': type
> Exception report message java.lang.Exception:
> java.lang.NoClassDefFoundError: org/apache/commons/lang3/StringUtils
> description The server encountered an internal error that prevented it from
> fulfilling this request. exception javax.servlet.ServletException:
> java.lang.Exception: java.lang.NoClassDefFoundError:
> org/apache/commons/lang3/StringUtils (libchurl.c:897) (seg9
> AYCAPSU01TS205:40000 pid=500623) (dispatcher.c:1801)
> ```
> We solved it by manually adding `/usr/local/lib/commons-lang3-3.1.jar` on
> Advanced pxf-public-classpath through Ambari. We were also to reproduce it
> internally just by following the example from the documentation
> (http://hdb.docs.pivotal.io/212/hawq/pxf/JsonPXF.html).
> Also noticed the libraries loaded for pxf-service are 2.6 instead:
> ```[root@hdp1 ~]# pgrep -fl pxf-service | cut -f1 -d' ' | xargs lsof -p |
> grep commons-lang
> java 372246 pxf mem REG 8,2 284220 1319168
> /usr/hdp/2.5.0.0-1245/hadoop/lib/commons-lang-2.6.jar
> java 372246 pxf 62r REG 8,2 284220 1319168
> /usr/hdp/2.5.0.0-1245/hadoop/lib/commons-lang-2.6.jar
> ```
> So for some reason PXF needs `commons-lang3-3.1.jar`?
