> Key: PHOENIX-3208

> Project: Phoenix
> Issue Type: Bug
> Affects Versions: 4.8.0
> Reporter: chenglei
>
> MutationState.toMutations method is to return the current uncommitted
> tables mutations , but if multiple tables have been upserted , the
> toMutations method would throw a exception:
> {code:borderStyle=solid}
> java.util.NoSuchElementException

> I write a simple unit test to reproduce this problem in my patch,the
> PhoenixRuntime.getUncommittedDataIterator method internally uses the
> MutationState.toMutations method:
> {code:borderStyle=solid}
> @Test
> public void testToMutationsError() throws Exception {
> Connection conn = null;
> try {
> conn=DriverManager.getConnection(getUrl());
> conn.createStatement().execute(
> "create table MUTATION_TEST1"+
> "( id1 UNSIGNED_INT not null primary key,"+
> "appId1 VARCHAR)");
> conn.createStatement().execute(
> "create table MUTATION_TEST2"+
> "( id2 UNSIGNED_INT not null primary key,"+
> "appId2 VARCHAR)");
> conn.createStatement().execute("upsert into
> MUTATION_TEST1(id1,appId1) values(111,'app1')");
> conn.createStatement().execute("upsert into
> MUTATION_TEST2(id2,appId2) values(222,'app2')");
> Iterator<Pair<byte[],List<KeyValue>>>
> dataTableNameAndMutationKeyValuesIter =
> PhoenixRuntime.getUncommittedDataIterator(conn);
> assertTrue(dataTableNameAndMutationKeyValuesIter.hasNext());
> Pair<byte[],List<KeyValue>>
> pair=dataTableNameAndMutationKeyValuesIter.next();
> String tableName1=Bytes.toString(pair.getFirst());
> List<KeyValue> keyValues1=pair.getSecond();
> assertTrue(dataTableNameAndMutationKeyValuesIter.hasNext());
> pair=dataTableNameAndMutationKeyValuesIter.next();
> String tableName2=Bytes.toString(pair.getFirst());
> List<KeyValue> keyValues2=pair.getSecond();
> if("MUTATION_TEST1".equals(tableName1)) {
> assertTable(tableName1, keyValues1, tableName2, keyValues2);
> }
> else {
> assertTable(tableName2, keyValues2, tableName1, keyValues1);
> }
> assertTrue(!dataTableNameAndMutationKeyValuesIter.hasNext());
> }
> finally {
> if(conn!=null) {
> conn.close();
> }
> }
> }
> {code}
