sharan-malyala opened a new issue, #39780:
URL: https://github.com/apache/beam/issues/39780
### What happened?
In `CassandraIO`, when a worker fails to connect to Cassandra database while
processing a work item, it throws an exception (like
`NoHostAvailableException`) [1] and the work item fails. However, it was
observed that all the subsequent work items ran on the same worker fail
immediately with an `IllegalStateException` [2] without even attempting to
connect to the database.
If a failed work item attempts all its leases on same worker, the entire job
is failing due to a transient connectivity issue.
[1] - Initial Exception
```com.datastax.driver.core.exceptions.NoHostAvailableException: All host(s)
tried for query failed...
