Hi,
I'm working with compressions in Hadoop,idea is to compress the file in
Linux then to process the same in Hadoop and to decompress it to Linux. I'm
able to do this for gzip and bzip2 *but when i tried for default
compression, I'm able to compress the file but it didn't work for decompress
i.e,
seems the user you used to run hive (sgehlot) has no write permission
for that hdfs directory
check your hadoop acl settings
regards

Because "^^ " may not appear in my data, so your regular expression doesn't
meet my need.
I tried and the result is not right.
Thank you.

My data format is as follows:

c&&&d^
My data format is as follows:

With SERDEPROPERTIES (
"input.regex"="(.+)&&&(.+)(\^\^.+)?"

My aim is :
a b
c b
c d
However ,

c b^^xyz
c d^^hdo
So how to
