Can NOT select from external tables on S3 after upgrading to CDH 5.3.2

[#1]

After I upgrade from CDH 5.3.1 to CDH 5.3.2, and then run "select" SQL queries, it gives me some errors:

select * from my_table limit 10;

FAILED: SemanticException Unable to determine if s3n://my-bucket/is encrypted: java.lang.IllegalArgumentException: Wrong FS: s3n://my-bucket/, expected: hdfs://us0701aohc172018080109.tangome.gbl:8020

I tryied to drop my table and re-create it again add partitions to it, then run select queries, still the same error. Before upgrading everything is OK.

Does anybody happen to know why?

Hi,

You just hit a bug related with the encryption changes added to CDH 5.3.2. This happens because an internal function is trying to check if the table location is encrypted or not. This works only for HDFS files, but not for external locations.

I'm afraid the only way to make it work is to downgrade to CDH 5.3.1. I don't see a workaround to bypass this error.

The next CDH 5.4.0 version will include this bugfix.

Thank you for telling me this, you really save my day!

You're welcome. Btw, we're expecting to have this fix for 5.3.3 instead.

How to downgrade?

By following the http://www.cloudera.com/content/cloudera/en/documentation/core/v5-2-x/topics/cdh_ig_install_previous...

It does not work for me. I am using ubuntu trusty. 

Although I specified the 5.3.1 version, apt-get install hive failure. 

If I do not specified the version, it will install 5.3.2

have the same issue on an external table in CDH 5.3.3

Error while compiling statement: FAILED: SemanticException Unable to determine if hdfs://cdhtest/store/TPCH3TB/lineitem is encrypted: java.lang.IllegalArgumentException: Wrong FS: hdfs://cdhtest/store/TPCH3TB/lineitem, expected: hdfs://pupa

any workaround ? is it fixed in 5.4

Hi,

This issue has been fixed on 5.3.3 and 5.4.0.

[#9]

Thanks, I'll upgrade my cluster and try it again

This is still not working for me. I am currently using cdh-5.4.3 for hive and impala

Despite the above comments about 5.3.3 and 5.4.0, this issue is not fixed in those versions. According to the comments from Jim B on a related thread of mine ( http://community.cloudera.com/t5/Batch-SQL-Apache-Hive/Loading-to-S3-Fails-CDH-5-3-0/m-p/24088#U2408... ) this _IS_ fixed in 5.4.4
