Description

I am seeing the following error when doing an INNER JOIN of a view with MULTI_TENANT=true with any other table or view:
java.lang.RuntimeException: org.apache.phoenix.exception.PhoenixIOException: org.apache.phoenix.exception.PhoenixIOException: org.apache.hadoop.hbase.DoNotRetryIOException: Could not find hash cache for joinId: Ys�0��%�. The cache might have expired and have been removed.

This is with Phoenix version 4.6.0 and HBase version 0.98.4.2.2.6.0-2800-hadoop2.

This seems very strongly related to the MULTI_TENANT=true property on a view or table. I see the error whenever the view has MULTI_TENANT=true and I have a tenant-specific connection to Phoenix. I do not see the problem if the MULTI_TENANT=true property is not set on the view or if I do not have a tenant-specific connection to Phoenix.

Here is an example SQL statement that has this error when the view INVENTORY has the MULTI_TENANT=true property and I have a tenant-specific connection, but that succeeds in other cases. (The view PRODUCT_IDS is not Multi-Tenant.)
SELECT * FROM INVENTORY INNER JOIN PRODUCT_IDS ON (PRODUCT_ID = INVENTORY.ID)

Note: "INNER JOIN" fails under these conditions, as does "LEFT OUTER JOIN". However, "RIGHT OUTER JOIN" and "FULL OUTER JOIN" do work. Also, if I tell Phoenix to use a Sort Join for the Inner Join or Left Outer Join then it does work, e.g. SELECT /*+ USE_SORT_MERGE_JOIN*/ * FROM INVENTORY INNER JOIN PRODUCT_IDS ON (PRODUCT_ID = INVENTORY.ID); works.

This seems to be the same problem that was discussed previously in this mailing list: https://mail-archives.apache.org/mod_mbox/phoenix-user/201507.mbox/[e-mail]%3E
