> spark-class gets syntax error in posix mode
> -------------------------------------------
>
> Key: SPARK-20546
> URL: https://issues.apache.org/jira/browse/SPARK-20546
> Project: Spark
> Issue Type: Bug
> Components: Deploy
> Affects Versions: 2.0.2
> Reporter: Jessie Yu
> Priority: Minor
> Fix For: 2.2.1, 2.1.2

> spark-class gets the following error when running in posix mode:
> {code}
> spark-class: line 78: syntax error near unexpected token `<'
> spark-class: line 78: `done < <(build_command "$@")'
> {code}
> \\
> It appears to be complaining about the process substitution:
> {code}
> CMD=()
> while IFS= read -d '' -r ARG; do
> CMD+=("$ARG")
> done < <(build_command "$@")
> {code}
> \\
> This can be reproduced by first turning on allexport then posix mode:
> {code}set -a -o posix {code}
> then run something like spark-shell which calls spark-class.
> \\
> The simplest fix is probably to always turn off posix mode in spark-class
> before the while loop.
> \\
> This was previously reported in
> [SPARK-8417|https://issues.apache.org/jira/browse/SPARK-8417] which closed
> with cannot reproduce.
