As a followup to my initial post regarding Apache Pig’s inability to quickly load many small files in Pig 0.10 and newer, I wanted to share a simple fix that worked for me courtesy of in-depth research by Amazon Support Team (+ Engineers). Basically around Pig 0.10.0, PigStorage builds a hidden schema file in an… Continue reading→

Sometimes I have data that is simply too large to store on one volume uncompressed, but I need to run processes on it. In my recent use case, I had one large Tar GZIPPED file that decompressed into many smaller tar gzipped files, which then decompressed into two column text (both strings). I did not… Continue reading→
