             Summary: Two gpg related errors when doing hadoop release
                 Key: HADOOP-15590
                 URL: https://issues.apache.org/jira/browse/HADOOP-15590
             Project: Hadoop Common
          Issue Type: Bug
            Reporter: Yongjun Zhang


When doing 3.0.3 release, by running command

dev-support/bin/create-release --asfrelease --docker --dockercache

documented in

https://wiki.apache.org/hadoop/HowToRelease

I hit the following problems:

1. 
{quote}
starting gpg agent ERROR: Unable to launch or acquire gpg-agent. Disable signing.
{quote}
The script expect GPG_AGENT_INFO env being set with needed info by the gpg-agent. However, it was not. This is because of changes made in gpg-agent. I found the workaround is to add the following line to dev-support/bin/create-release script right after starting gpg-agent:
{quote}
export GPG_AGENT_INFO="~/.gnupg/S.gpg-agent:$(pgrep gpg-agent):1"
{quote}

2.
{quote}
gpg: can't connect to `~/.gnupg/S.gpg-agent': invalid value
{quote}
I found that this is caused by unmatching gpg-agent and gpg versions installed via Docker. I modified dev-support/docker/Dockerfile to install gnupg2 instead of gnupg. This made gpg and gpg-agent both 2.1.11 instead of one on 2.1.11 the other on 1.14. And this solved the above problem.
