Description

This is to address the addendum of HCATALOG-621, now that the HCatalog jira seems to be in read-only mode. To quote Nick from the original bug:

I'm not sure how this fixes anything for the error listed above. The find command in the script we merged is broken, at least on linux. Maybe it worked with BSD find and we both tested on Macs?

From the patch we committed:

if [ -d ${HBASE_HOME} ] ; then
   for jar in $(find $HBASE_HOME -name *.jar -not -name thrift\*.jar); do
      HBASE_CLASSPATH=$HBASE_CLASSPATH:${jar}
   done
   export HADOOP_CLASSPATH="${HADOOP_CLASSPATH}:${HBASE_CLASSPATH}"
fi

The find command syntax is wrong – it returns no jars ever.

$ find /usr/lib/hbase -name *.jar
$ find /usr/lib/hbase -name *.jar -not -name thrift\*.jar
$

What we need is more like:

$ find /usr/lib/hbase -name '*.jar'
... // prints lots of jars
$ find /usr/lib/hbase -name '*.jar' | grep thrift
/usr/lib/hbase/lib/libthrift-0.9.0.jar
$ find /usr/lib/hbase -name '*.jar' -not -name '*thrift*' | grep thrift
$
