Description

Jira Link: DB-3757

Permissions for “index.000000000” in all the tables/tablets wal folders is not consistent with rest of the files in those folders.

example:

[yugabyte@ip-XXX table-xxxxxxxxxxxxxxxxx]$ ls -lrt * tablet-8159e249b418495aa9a898ec5b005f22: total 2088 -rw-------. 1 yugabyte yugabyte 1048576 Sep 28 09:54 wal-000000021 -rw-rw-r--. 1 yugabyte yugabyte 24000000 Sep 29 10:56 index.000000000 -rw-------. 1 yugabyte yugabyte 1048576 Sep 29 10:56 wal-000000022

Contributor guide

Research direction
Look at the code that creates the 'index.000000000' file in the WAL directory and ensure it uses the same file permissions as other WAL files (e.g., 'wal *' files). The fix likely involves changing the file creation mode mask or explicitly setting permissions via fchmod.
