-----------------------------------------------------------------
What's happening is the index table still has rows from the prior iteration.
So I think there's something wrong with the "DELETE FROM". Although what's odd
is when I query the counts immediately after the DELETE statements, I get 0 as
expected.
Seems like maybe a raw scan somewhere is picking up the old rows and reindexing
them?

> Key: PHOENIX-4980
> URL: https://issues.apache.org/jira/browse/PHOENIX-4980
> Project: Phoenix
> Issue Type: Bug
> Affects Versions: 4.14.0
> Reporter: Abhishek Talluri
> Priority: Major
> Labels: LocalIndex, globalMutableSecondaryIndex, secondaryIndex
> Attachments: TestSecIndex.java
>
>
> Phoenix table has A,B,C,D,E as its columns and A as the primary key for the
> table.
> CREATE TABLE TEST (A VARCHAR NOT NULL PRIMARY KEY, B VARCHAR, C VARCHAR, D
> VARCHAR , E VARCHAR);
> Global index is built on D & E
> CREATE INDEX TEST_IND on TEST (D,E);
> Client 1 updates A,B,C whereas client 2 updates A,B,D,E
> I used phoenix 5.14.2-1.cdh5.14.2.p0.3 parcel to test this issue. Ran with
> two threads that load data using upserts reading from the csv file. Within 10
> iterations, i could observe the difference in the row counts between data
> table and index table. Attaching the code used to test this behavior. This
> issue also exists in both Global and Local indexes.
