Cannot run PIG from HUE

I have installed a 4 node cluster. The cluster is up and running. I’m able to load data and run queries. However I’m not able to run PIG scripts. I get the error :
ls: cannot access /grid/1/hadoop/yarn/local/usercache/hue/appcache/application_1409126352550_0003/container_1409126352550_0003_01_000002
/hive.tar.gz/hive/lib/slf4j-api-*.jar: No such file or directory
Error: Could not find or load main class hive.metastore.uris=thrift:..localhost:9933
Please suggest ways to resolve this issue.
Thanks,
