     [ https://issues.apache.org/jira/browse/HIVE-22055?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Attila Magyar updated HIVE-22055:
---------------------------------
    Description: 
Add one more load to mm_loaddata.q:

Load data 3 times (both kv1.txt and kv2.txt contains 500 records)
{code:java}
create table load0_mm (key string, value string) stored as textfile tblproperties("transactional"="true",
"transactional_properties"="insert_only");
load data local inpath '../../data/files/kv1.txt' into table load0_mm;
select count(1) from load0_mm;
load data local inpath '../../data/files/kv2.txt' into table load0_mm;
select count(1) from load0_mm;
load data local inpath '../../data/files/kv2.txt' into table load0_mm;
select count(1) from load0_mm;{code}
Expected output
{code:java}
PREHOOK: query: load data local inpath '../../data/files/kv2.txt' into table load0_mm
PREHOOK: type: LOAD
#### A masked pattern was here ####
PREHOOK: Output: default@load0_mm
POSTHOOK: query: load data local inpath '../../data/files/kv2.txt' into table load0_mm
POSTHOOK: type: LOAD
#### A masked pattern was here ####
POSTHOOK: Output: default@load0_mm
PREHOOK: query: select count(1) from load0_mm
PREHOOK: type: QUERY

POSTHOOK: query: select count(1) from load0_mm
POSTHOOK: type: QUERY
POSTHOOK: Input: default@load0_mm
#### A masked pattern was here ####
1500{code}
Got:

[ERROR]   TestMiniLlapLocalCliDriver.testCliDriver:59 Client Execution succeeded but contained
differences (error code = 1) after executing mm_loaddata.q
