We tried to upgrade a hive single node from 2.1.1 to 2.3.7 and use derby as the database. After upgrade, Hive log keeps printing the following Error message repeatedly:

We did use schematool to upgrade Hive. The log also shows that upgrade metastore is performed. Here are the steps to reproduce it:
1. Start up a standalone hive node of version 2.1.1 using embedded derby, and use schematool to initialize the schema.
2. Use the following shell script to generate 20k data.
{code:java}
rm -rf ./data.txt
touch data.txt
for((i=0;i<20000;i++))
do
str=',name';
name=${i}${str}${i}
echo $name>> data.txt
done
{code}
3. Create a table and load data by using:
{code:java}
create table testTable(id int,name string) row format delimited fields terminated by ',';
LOAD DATA LOCAL INPATH '/data.txt' OVERWRITE INTO TABLE testTable;
{code}
4. We stopped the nodes, and started a node running hive compiled from 2.3.7, while keeping the node of hadoop running.
5. Run the following command to upgrade schema.
{code:java}
schematool -dbType derby -upgradeSchema
{code}
Log shows that metastore is being upgraded:

6. However, after upgrade, the log still keeps printing the previous Error message with exception - "Hive Schema version 2.3.0 does not match metastore's schema version 2.1.0”.
