Edward Capriolo commented on HIVE-4562:
---------------------------------------
I just upgraded to hive 0.10 and I had to but these in the auxlib.
We REALLY need to start using jar jar here. The bigger hive-exec gets the more
painful its gets to build udfs. In particular if a udf or input format uses
jackson the target library needs to match the version. This is already a
problem because things like apache-commons get built into hive-exec . So if ANY
other project you are trying to use leverages commons you are forced to use
hive's version in some cases.
> HIVE-3393 brought in Jackson library,and these four jars should be packed
> into hive-exec.jar

> Some jars of Hive are required not only by the client but also the server
> (every Hadoop slave),
> though we could use 'add jar' command to add all the jars in dis-cache ,
> but in common way ,we may add these jars in $HADOOP_HOME/lib/ of every salve
> of the Hadoop Cluster,
> and need restart all the tasktrackers .
> For example:
> When using hive stats, If we use mysql as tmp stats db ,every salve of the
> Hadoop Cluster should contain
> mysql-connector-java-****.jar in $HADOOP_HOME/lib/
> And for column stats
> In all slaves $HADOOP_HOME/lib/ should contain:
> jackson-core-asl-1.8.8.jar
> jackson-jaxrs-1.8.8.jar
> jackson-mapper-asl-1.8.8.jar
> jackson-xc-1.8.8.jar
> These jars should be separated from other common client-side-jars .
