I don't think this is expected behaviour, but where the bug is what I'm looking into. > We have a custom StorageHandler that we're updating from Hive 1.2.1 to Hive > 3.0.0. Most likely this bug existed in Hive 1.2 as well, but the FetchTask conversion did not happen for these queries. I'll probably test out your SerDe tomorrow, but I have two target cases to look into right now. The first one is that this is related to a different issue I noticed with Hadoop-Common code (i.e a direct leak). https://issues.apache.org/jira/browse/HADOOP-10513 The second one is that this is only broken with the Local FetchTask (which gets triggered when you run "select ... limit n"). > SELECT * FROM my_ext_table; So those theories, I recommend trying out set hive.fetch.task.conversion=none; and running the same query so that the old Hive1 codepaths for reading from the SerDe get triggered.
