Re: Urgent problem with Phoenix function LAST_VALUE and joins
Sounds like a plan thanks.
Is there any doco to help with getting setup? I assume the phoenix dev channel
is the place to ask questions.

Geoffrey,
Thank you for pointing out this. I mixed up release numbers. Yes, the paging
feature cannot be the reason here. My comment for disabling the paging feature
should be ignored.

Kadir,
The server-side paging changes are in Phoenix 5.1, which is at feature parity
with 4.16 for HBase 1.x, not 5.0 (which was released in 2018 and is roughly
equivalent to Phoenix 4.14).
So if Simon's environment is Phoenix 5.0, it can't be affected by the
server-side changes. (Though I see that he's running HBase 2.2, which I thought
wasn't supported until Phoenix 5.1?)

Subject: Re: Urgent problem with Phoenix function LAST_VALUE and joins
In Phoenix 5.0 we introduced a new server side paging feature to eliminate
timeouts due long running server side computations such aggregation and joins.
I wonder if this new feature caused your issue. If so, the work around is to
disable it by setting phoenix.server.paging.enabled to false in hbase-site.xml.
This is a client side config param so you just need to restart your client.
Hope this will fix your issue.

Hi
Got my fingers crossed that there's a work around for this as this really is a
big problem for us
We are using:
Amazon EMR
Release label:emr-6.1.0
Hadoop distribution:Amazon

Thin Client version:
phoenix-5.0.0-HBase-2.0-thin-client.jar
We get the following error when doing an LAST_VALUE aggregation where
1. A JOIN is empty
2. The column is INTEGER or DATETIME
Remote driver error: IllegalArgumentException: offset (25) + length (4) exceed
the capacity of the array: 25
The query that breaks is:
SELECT
"BIOMATERIAL_NAME",
FIRST_VALUE("PLANT_FRUIT_COUNT") WITHIN GROUP (
ORDER BY OBSERVATION_DATE DESC) AS "Plant Fruit Count"
FROM
VARIABLE_VALUES_QA.OBSERVATION
JOIN VARIABLE_VALUES_QA.OBSERVATION_TAG_INDEX
ON DOCID = OBSERVATION_VALUE_ID
AND TAGNAME = 'TRIAL_ID'
AND TAGVALUE = 'f62dd8e0-d2ea-4d9a-9ab6-2049601bb9fe'
GROUP BY
"BIOMATERIAL_NAME"
LIMIT 10
OFFSET 0;
I can refactor this using EXIST but get same error, presumably the driver knows
to treat them the same:
SELECT
"BIOMATERIAL_NAME",
FIRST_VALUE("PLANT_FRUIT_COUNT") WITHIN GROUP (
ORDER BY OBSERVATION_DATE DESC) AS "Plant Fruit Count"
FROM
VARIABLE_VALUES_QA.OBSERVATION
WHERE
EXISTS (

DOCID

VARIABLE_VALUES_QA.OBSERVATION_TAG_INDEX
WHERE
DOCID = OBSERVATION_VALUE_ID

AND TAGVALUE = 'f62dd8e0-d2ea-4d9a-9ab6-2049601bb9fe')
GROUP BY
"BIOMATERIAL_NAME"
LIMIT 10
OFFSET 0;
If we remove the external reference we get no error, regardless of whether
there are any hits or not
-- these all work
There are no hits for this query
SELECT
"BIOMATERIAL_NAME",
FIRST_VALUE("PLANT_FRUIT_COUNT") WITHIN GROUP (

Lots of hits for this query:

FROM
VARIABLE_VALUES_QA.OBSERVATION

Re: Urgent problem with Phoenix function LAST_VALUE and joins
There seem to be no obvious unsubscribe to this list. Unlike all other Apache
lists. Given that we have (thank God) decommissioned all our Phoenix instances
how do I delete myself from this list?

Next Tech Talk on Online Data Format Change in Phoenix
Hi All, Did you ever need to change the underlying data format of your table which is already in production and serving your customers. For example, you wanted to change the primary key of your table, or its column encoding or even its storage format. And you wanted to do this without interrupting the services depending on this table. If you did, then you would want to attend the tech talk by Gokcen Iskender on Oct 07 (next Thursday at 9:00 PST) and see how this will be possible in Phoenix. Hope to see you there. Please see details at https://phoenix.apache.org/tech_talks.html. Thanks, Kadir

Please try to reproduce with the latest released Phoenix version, or git
master HEAD before opening the JIRA.
You can use bin/phoenix_sandbox.py in the source repo/distribution to
quickly start a test environment without installing Phoenix in a real
cluster.
