Hi, Could you help me to run a pig script with successful status. As mentioned in the Lab 3 exercise, geolocation table was created in hive and the pig script was created with only load transformation. a = LOAD 'geolocation' using org.apache.hive.hcatalog.pig.HCatLoader(); DUMP a LIMIT 1; Tried executing the script(not on Tez) arguments with -useHCatalog. In the ResourceManagerUI the status show succeeded with Cantainers allocated 2. But, in the PIGUI the status is still RUNNING. It neither errors or return a result tab. What might be the issue? How to check if the metadata exist in HCatalog? WebHCat server is in started status. Where should I look for Heap memory?
