Tarun Parimi updated YARN-10007:
--------------------------------
Issue Type: New Feature (was: Bug)
> YARN logs contain environment variables, which is a security risk
> -----------------------------------------------------------------
>
> Key: YARN-10007
> URL: https://issues.apache.org/jira/browse/YARN-10007
> Project: Hadoop YARN
> Issue Type: New Feature
> Components: yarn
> Reporter: john lilley
> Priority: Major
>
> In most environments it is standard practice to relay "secrets" via
> environment variables when spawning a process, because the alternatives
> (command-line args or storing in a file) are insecure. However, in a YARN
> application, this also appears to be insecure because the environment is
> logged. While YARN has the ability to relay delegation tokens in the launch
> context, it is unclear how to use this facility for generalized "secrets"
> that may not conform to security-token structure.
> For example, the RPDM_KEYSTORE_PASSWORDS env var is found in the aggregated
> YARN logs:
> {{Container: container_e06_1574362398372_0023_01_000001 on
> node6.xxxxxxxx.com_45454}}
> {{LogAggregationType: AGGREGATED}}
> {{============================================================================================}}
> {{LogType:launch_container.sh}}
> {{LogLastModifiedTime:Sat Nov 23 14:58:12 -0700 2019}}
> {{LogLength:4043}}
> {{LogContents:}}
> {{#!/bin/bash}}{{set -o pipefail -e}}
> {{[...]export
> HADOOP_YARN_HOME=${HADOOP_YARN_HOME:-"/usr/hdp/2.6.5.1175-1/hadoop-yarn"}}}
> {{export
> RPDM_KEYSTORE_PASSWORDS="eyJnZW5lcmFsIjoiZmtQZllubmVLRVo4c1Z0V0REQ3gxaHJzRnVjdVN5b1NBTE9OUTF1dEZpZ1x1MDAzZCJ9"}}
