Ashutosh Gupta updated HADOOP-18327:
------------------------------------
Description:
Need to fix the eval expression. We can relace single quote with escape-char
and a double quote.
HADOOP_OPTS can contain -XX:OnOutOfMemoryError='kill -9 %p', this leads to
following invalid eval expression - eval $HADOOP_OPTS='foo_bar
-XX:OnOutOfMemoryError='kill -9 %p''

Replacing with escape-char and a double quote should works fine.
eval "$1"="'${!1} $3'" -> eval "$1"="\"${!1} $3\""
eval "$1"="'${!1# }'" -> eval "$1"="\"${!1# }\""
