---------------------------------
Summary: 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
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.
