Please help. After reading tons of posts and pages, and making memory adjustments and other manipulations, Pig example is stuck at 0%. Please any ideas?
Several discussions suggested adding more memory to YARN, did not help. Cluster: 1 server with 16GB RAM and 3 servers with 8GB RAM.
The stock Pig example does not work neither from Hue nor from Grunt.
This is the example:
data = LOAD '/user/hue/pig/examples/data/midsummer.txt' as (text:CHARARRAY);
upper_case = FOREACH data GENERATE UPPER(text);
STORE upper_case INTO '$output' ;
This is the last line of output:

Hi Grenoble, Alxrud,
Thanks for bringing this to our attention. Given the details of the reported problem, I attempted to reproduce the same issue spinning up a cluster, and was able to successfully run the Pig script in Hue (as shown below, including cluster configuration steps):
1) Setup test cluster with Cloudera Express CM 5.4.1, CDH 5.3.0 (Parcels)
