Now I get it, thanks for clarification. Yes, the issue might be with spaces:
likely with with $JAVA. What value it has on your environment?

Now I get it, thanks for clarification. Yes, the issue might be with spaces:
likely with with $JAVA. What value it has on your environment?
If I am correct, the solution can be to add in drillbit.sh (line 388)
*JAVA=`cygpath -w "$JAVA"`*:
{code}
# Adjust paths for CYGWIN
if $is_cygwin; then
JAVA=`cygpath -w "$JAVA"`
DRILL_HOME=`cygpath -w "$DRILL_HOME"`
DRILL_CONF_DIR=`cygpath -w "$DRILL_CONF_DIR"`
DRILL_LOG_DIR=`cygpath -w "$DRILL_LOG_DIR"`
DRILL_TMP_DIR=`cygpath -w "$DRILL_TMP_DIR"`
CP=`cygpath -w -p "$CP"`
if [ -z "$HADOOP_HOME" ]; then
export HADOOP_HOME=${DRILL_HOME}/winutils
fi
fi
{code}
Can you please check if it helps?
