> 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 .
