Re: Issue while quering Hive
With regards to splitting an compression there are 2 options really as of now If u r using Sequence Files , then Snappy If u r using TXT files then LZO us great (u have to cross a few minor hoops to get LZO to work and I can provide guidance on that) Please don't use GZ (not splittable) / or worse BZ2 (took slow to compress/decompress) - too slow for comfort The only compelling reason u want to use GZIP as I am using in production is that my log files are MULTIPLE LINES…so if I use regular TXT files then splitting can happen between records sanjay From: Nitin Pawar mailto:nitinpawar...@gmail.com>> Reply-To: "user@hive.apache.org<mailto:user@hive.apache.org>" mailto:user@hive.apache.org>> Date: Monday, September 16, 2013 5:07 AM To: "user@hive.apache.org<mailto:user@hive.apache.org>" mailto:user@hive.apache.org>> Subject: Re: Issue while quering Hive As per my understanding, hadoop 1.x does not provide you any help on processing compressing files in parallel manner.
