> Right now, custom cluster tests only allow specifying impalad startup options, however, it would be nice if the tests could specify arbitrary HDFS client configs as well (e.g. {{dfs.client}} options). This would allow us to increase our test integration coverage with different HDFS client setups such as (1) disabling short-circuit reads (thus triggering the code path for a remote read) (requires setting {{dfs.client.read.shortcircuit}} to false), (2) enabling hedged reads (requires setting {{dfs.client.hedged.read.threadpool.size}} to a value greater than 0).
