4@SUDARSHAN My function above works with uncompressed data. In your example I think you are using gzip compression as you write files - and then after - trying to merge these together which fails. That isn't going to work, as you can't merge gzip files together. Gzip is not a Splittable Compression algorithm, so certainly not "mergable". You might test "snappy" or "bz2" compression - but gut feel is this will fail too on merge. Probably best best is to remove compression, merge raw files, then compress using a splittable codec.Minkymorgan– Minkymorgan2017-10-23 17:04:50 +00:00Commented Oct 23, 2017 at 17:04

How to Tag
A tag is a keyword or label that categorizes your question with other, similar questions. Choose one or more (up to 5) tags that will help answerers to find and interpret your question.
- complete the sentence: my question is about...
- use tags that describe things or concepts that are essential, not incidental to your question
- favor using existing popular tags
- read the descriptions that appear below the tag
If your question is primarily about a topic for which you can't find a tag:
- combine multiple words into single-words with hyphens (e.g. python-3.x), up to a maximum of 35 characters
- creating new tags is a privilege; if you can't yet create a tag you need, then post this question without it, then ask the community to create it for you
