Eugene Koifman reassigned HIVE-17295:
-------------------------------------
> Make MemoryManagerImpl.ROWS_BETWEEN_CHECKS configurable
> -------------------------------------------------------
>
> Key: HIVE-17295
> URL: https://issues.apache.org/jira/browse/HIVE-17295
> Project: Hive
> Issue Type: Bug
> Reporter: Eugene Koifman
> Assignee: Eugene Koifman
>
> currently addedRow() looks like
> {noformat}
> public void addedRow(int rows) throws IOException {
> rowsAddedSinceCheck += rows;
> if (rowsAddedSinceCheck >= ROWS_BETWEEN_CHECKS) {
> notifyWriters();
> }
> }
> {noformat}
> it would be convenient for testing to set ROWS_BETWEEN_CHECKS to a low value
> so that we can generate multiple stripes with very little data.
> Currently the only way to do this is to create a new MemoryManager that
> overrides this method and install it via OrcFile.WriterOptions but this only
> works when you have control over creating the Writer.
> There is no way to do this via some set of config params to make Hive query
> for example, create multiple stripes with little data.
