AvroStorage

Expert Contributor

Hi,

I use AvroStorage to store relation into avro file, when i dont specify any path inside the STORE all works fine, but when path is explicitly specified then im occurring strange error related to the permissions.... any idea? I run pig in local mode, why is there hdfs issue?

using stamement without specifiyng the path, all works fine.

STORE A INTO 'xyz-CustomerData-20160120-1101174-ttp'

using statement below i got error:

STORE A INTO '/root/xyz-CustomerData-20160120-1101174-ttp'

@John Smith what user are you executing as? Show the command you're executing.

Re: AvroStorage

Expert Contributor

@Artem Ervits as user root (uid=0), doesnt matter what dir is it.

I tried

chomod 777 /avro-out/
STORE A INTO '/avro-out/xyz-CustomerData-20160120-1101174-ttp'

The same error occured.

Re: AvroStorage

Expert Contributor

Im wondering why HDFS is involved in the output error, im executing pig script in -x local mode.

Re: AvroStorage

Mentor

can you execute it using "pig -x tez_local script". Replace /root and /avro-out with /tmp. @John Smith
