Solution:

Which unzip should point to $ORACLE_HOME/bin/unzip

Take the backup of existing unzip from $ORACLE_HOME/bin

cd $ORACLE_HOME/bin

mv unzip unzip_bkp

Copy /usr/bin/unzip to $ORACLE_HOME/BIN

 cp -rp  /usr/bin/unzip $ORACLE_HOME/bin

Make sure the unzip utility under /usr/bin should be of version 5.X and not 6

Retest the issue by running adcfgclone.pl dbTier
