-------------------------------------
Summary: BloomK Filter probing method is not thread safe
Key: HIVE-20893
URL: https://issues.apache.org/jira/browse/HIVE-20893
Project: Hive
Issue Type: Bug
Components: storage-api
Reporter: slim bouguerra
As far i can tell this is not an issue for Hive yet (most of the usage of
probing seems to be done by one thread at a time) but it is an issue of other
users like Druid as per the following
issue.[https://github.com/apache/incubator-druid/issues/6546]
The fix is proposed by the author of
[https://github.com/apache/incubator-druid/pull/6584] is to make couple of
local fields as ThreadLocals.
Idea looks good to me and doesn't have any perf drawbacks.
