Hello,
I am running in some huge performance issues when I want to query my orc files stored on S3 with Hive 0.12. My orc files have a stripe size of 16 MB - this might be a problem when it comes to read performance, but it can't be the only reason. I was running a simple query on ~600GB ORC Data and it took a 16 node cluster about 2hrs to perform ~5% of the Job. Are there any known issues for the hive orcreader? My create statement looks like this CREATE external TABLE externalORC (..) STORED AS ORC location 's3n://./'; Kind regards, Thomas
