Alan Gates commented on PIG-115:
--------------------------------
I found the cause for both the reduplication and the failure to run.
The reduplication is caused by line 50: bin=`cd "$bin"; pwd`
In my bash (Red Hat Linux) if CDPATH is set, then cd returns the name of the
directory it is switching to. This causes the above line to print the name of
the directory you're switching to twice. So the line should be changed to
something like: bin=`unset CDPATH; cd "$bin"; pwd`
The failure comes from a couple of issues:
1) Line 110, which reads: "for f in $PIG_HOME/pig-*-core.jar; do" should
instead read "for f in $PIG_HOME/build/pig-*-core.jar; do", as the pig jars are
in the build directory, not the top directory.
2) pig-*-core.jar does not contain all the necessary classes, or perhaps the
classpath is otherwise deficient. When I changed the line 110 to reference the
jar in the build directory, I get:
2008-03-04 12:49:15,036 [main] INFO
org.apache.pig.backend.hadoop.executionengine.HExecutionEngine - Connecting to
hadoop file system at: wilbur20.labs.corp.sp1.yahoo.com:8020
2008-03-04 12:49:15,280 [main] ERROR org.apache.pig.Main -
org.apache.pig.backend.executionengine.ExecException: Failed to create
DataStorage
If I change the line to instead read: "for f in $PIG_HOME/build/pig-*.jar; do"
then it all works.
