Procedure
To set up the umask:
-
Open a terminal.

Give read/write permission for new tables and data by editing the appropriate shell file for the DataStax Enterprise environment:
File Location dse-env.sh-
/etc/dse/ -
install_location/conf/
cassandra-env.sh-
/etc/dse/cassandra -
install_location/conf
-
-
Add the command
umask 002to the top of the file.Setting the umask to 002 is required because Cassandra creates new directories or files as 0700 by default, which does not grant read or write permissions.
