> If a {{BATCH}} statement contains multiple {{UPDATE}} statements that update the same partition, and a secondary index exists on that table, the batch statement will error:
> {noformat}
> ServerError: <ErrorMessage code=0000 [Server error] message="java.lang.IllegalStateException: An update should not be written again once it has been read">
> {noformat}
> with the following traceback in the logs:
> {noformat}
> ERROR 20:53:46 Unexpected exception during request
> java.lang.IllegalStateException: An update should not be written again once it has been read

> You can reproduce the issue with a table and index like this:
> {noformat}
> CREATE TABLE foo (a int, b int, c int, d int, PRIMARY KEY (a, b));
> CREATE INDEX ON foo(c);
> {noformat}
> and a batch update like this:
> {noformat}
> BEGIN BATCH
> UPDATE foo SET c = 0 WHERE a = 0 AND b = 0;
> UPDATE foo SET d = 0 WHERE a = 0 AND b = 0;
> APPLY BATCH
> {noformat}
> Assigning [~slebresne] for now, since he probably has the best idea of how to avoid this.
