Hi Team, Getting following error when trying to join 2 different tables with same table.

Hash collision on user-specified ID "uid_split_monitor_tableRoot". Most likely cause is a non-unique ID. Please check that all IDs specified via `uid(String)` are unique.
	at org.apache.flink.streaming.api.graph.StreamGraphHasherV2.generateNodeHash(StreamGraphHasherV2.java:185)
	at org.apache.flink.streaming.api.graph.StreamGraphHasherV2.traverseStreamGraphAndGenerateHashes(StreamGraphHasherV2.java:110)

Our Eg:

table1 = tableEnv.sqlQuery("");
table2 = tableEnv.sqlQuery("");

tableRoot = tableEnv.sqlQuery("");

table3= table1.join(tableRoot);
table4= table2.join(tableRoot)

Has anyone faces this ? Anything we are doing wrong here ? Appreciate any help. Thanks
