One small nitpick, the patch may be reduced on reliance on indirection by properly quote the condition check: {code} if [[ -n ${!uvar} ]]; then {code} into: {code} if [ -n "${uvar}" ]; then {code} > "hadoop CLASSFILE" prints error messages on Ubuntu 18 > ----------------------------------------------------- > > Key: HADOOP-16167 > URL: https://issues.apache.org/jira/browse/HADOOP-16167 > Project: Hadoop Common > Issue Type: Improvement > Components: scripts > Affects Versions: 3.2.0 > Reporter: Daniel Templeton > Assignee: Daniel Templeton > Priority: Major > Attachments: HADOOP-16167.001.patch > > > {noformat} > # hadoop org.apache.hadoop.conf.Configuration > /usr/lib/hadoop/bin/../lib/hadoop/libexec//hadoop-functions.sh: line 2366: > HADOOP_ORG.APACHE.HADOOP.CONF.CONFIGURATION_USER: bad substitution > /usr/lib/hadoop/bin/../lib/hadoop/libexec//hadoop-functions.sh: line 2331: > HADOOP_ORG.APACHE.HADOOP.CONF.CONFIGURATION_USER: bad substitution > /usr/lib/hadoop/bin/../lib/hadoop/libexec//hadoop-functions.sh: line 2426: > HADOOP_ORG.APACHE.HADOOP.CONF.CONFIGURATION_OPTS: bad substitution > {noformat} > The issue is a regression in bash 4.4.
