Hi,
I have 3 DCs out of which in one of the DC, I added 20 nodes. All of the DCs
had auth enabled, it was functioning fine. But after addition of 20 nodes in
one of the DC, the permissions just got messed-up on the existing nodes. My
application started getting errors while querying using the user it normally
did.
Finally, I logged onto one of the existing nodes that was operating fine and
issued the following cql query and it gave me the following error.
cqlsh:system_auth> select * from users;TSocket read 0 bytes
Upon investigation in system log I found the following exception, what does
this mean? Thanks.
