> Variable substitution can lead to OOM on circular references
> ------------------------------------------------------------
>
> Key: HIVE-22901
> URL: https://issues.apache.org/jira/browse/HIVE-22901
> Project: Hive
> Issue Type: Bug
> Components: HiveServer2
> Affects Versions: 3.1.2
> Reporter: Daniel Voros
> Assignee: Daniel Voros
> Priority: Major
> Attachments: HIVE-22901.1.patch, HIVE-22901.2.patch,

> {{SystemVariables#substitute()}} is dealing with circular references between
> variables by only doing the substitution 40 times by default. If the
> substituted part is sufficiently large though, it's possible that the
> substitution will produce a string bigger than the heap size within the 40
> executions.
> Take the following test case that fails with OOM in current master (third
> round of execution would need 10G heap, while running with only 2G):
> {code}
> @Test
> public void testSubstitute() {
> String randomPart = RandomStringUtils.random(100_000);
> String reference = "${hiveconf:myTestVariable}";
> StringBuilder longStringWithReferences = new StringBuilder();
> for(int i = 0; i < 10; i ++) {
> longStringWithReferences.append(randomPart).append(reference);
> }
> SystemVariables uut = new SystemVariables();
> HiveConf conf = new HiveConf();
> conf.set("myTestVariable", longStringWithReferences.toString());
> uut.substitute(conf, longStringWithReferences.toString(), 40);
> }
> {code}
> Produces:
> {code}
> java.lang.OutOfMemoryError: Java heap space
> at java.util.Arrays.copyOf(Arrays.java:3332)

> {code}
> We should check the size of the substituted query and bail out earlier.
