Subject: Re: Problem in finding the largest value of an indexed column

When I made more tests, I find that this problem happens after table got split.
Here is the DDL I use to create table and index:
CREATE TABLE IF NOT EXISTS t1 (
uid BIGINT NOT NULL,
timestamp BIGINT NOT NULL,
eventName VARCHAR
CONSTRAINT my_pk PRIMARY KEY (uid, timestamp)) COMPRESSION='SNAPPY';
CREATE INDEX timestamp_index ON t1 (timestamp) INCLUDE (eventName)
Attach is the sample data I used for test. It has about 4000 rows, when the timestamp_index table has one region, the query returns correct result: 1433334048443, but when I manually split it into 4 regions (use hbase tool), it returns 1433333024961.
