Summary: Fix SQL script in SQLServer/FederationStateStoreTables.sql
Key: YARN-11810
URL: https://issues.apache.org/jira/browse/YARN-11810
Project: Hadoop YARN
Issue Type: Bug
Components: federation
Affects Versions: 3.4.1
Reporter: Peter Szucs
Assignee: Peter Szucs
The SQLServer/FederationStateStoreTables.sql script contains duplicated create
statements and SQL syntax errors which makes
_TestFederationSQLServerScriptAccuracy#checkSqlServerScriptAccuracy_ unit test
fail.
I see 2 issues which cause this test failure:
# *Duplicated create statements*
** the test creates a SQLServerFederationStateStore class, which extracts and
stores the "CREATE TABLE" statements from FederationStateStoreTables.sql with
the [extractCreateTableSQL
method|https://github.com/apache/hadoop/blob/trunk/hadoop-yarn-project/hadoop-yarn/hadoop-yarn-server/hadoop-yarn-server-common/src/test/java/org/apache/hadoop/yarn/server/federation/store/impl/SQLServerFederationStateStore.java#L43].
** then iterates through the collected statements and executes them as a
prepared statement
[here|https://github.com/apache/hadoop/blob/trunk/hadoop-yarn-project/hadoop-yarn/hadoop-yarn-server/hadoop-yarn-server-common/src/test/java/org/apache/hadoop/yarn/server/federation/store/sql/TestFederationSQLServerScriptAccuracy.java#L53]
** the create statements for _masterKeys_ and _delegationTokens_ tables are
duplicated in the script, so these will be collected and attempted to be
executed twice, which results in the following error during the test runs:
{code:java}

# *Syntax errors in the SQL script*
** the create statements for _sequenceTable_ and versions are missing a comma
before the constraints are defined here:
{code:java}
CREATE TABLE [dbo].[sequenceTable](
sequenceName VARCHAR(255) NOT NULL,
nextVal bigint NOT NULL
CONSTRAINT [pk_sequenceName] PRIMARY KEY
(
[sequenceName]
)
){code}
and here:
{code:java}
CREATE TABLE [dbo].[versions](
fedVersion VARBINARY(1024) NOT NULL,
versionComment VARCHAR(255) NOT NULL
CONSTRAINT [pk_fedVersion] PRIMARY KEY
(
[fedVersion]
)
){code}
