Vikram Ahuja updated HIVE-29690:
--------------------------------
Description:
When we call HMSHandler.get_table_objects_by_name_req(req) HMS API on a
database with large number of tables(~5000) with pattern and tableNames. The
following exception is thrown in the HMS side:
{code:java}

This error is only seen when both tablepattern and tableNames are passed. If
either of them are null, then this issue does not occur.

*Root Cause: DataNucleus ExpressionCompiler Stack Overflow*
HIVE-24769 : getTableObjectsByName was refactored to support a flexible dynamic
filter builder (appendSimpleCondition). The original JDOQL contains() approach
was replaced with an explicit OR chain:
Old (Hive 3): "... && tbl_names.contains(tableName)"
→ SQL: WHERE tableName IN ('t1', 't2', ..., 'tN')
New (Hive 4): "tableName == :p1 || tableName == :p2 || ... || tableName ==
:pN"
→ one OR operator per table name
DataNucleus (the JDO/ORM layer used by HMS) parses JDOQL filter strings at
query creation time using a recursive descent parser. The relevant methods are
mutually recursive:
compileExpression()
└── compileOrAndExpression()
└── compileExpression() ← recurses back
└── compileOrAndExpression()
...
Every || operator in the filter string consumes one Java stack frame. With 5000
tables:
- getTableObjectsByName builds a filter with 4999 || operators and 10,000
bound parameters
- DataNucleus attempts to parse this at pm.newQuery(...) time
- ~10,000 stack frames are consumed → StackOverflowError
when tablePattern is sent as NULL then batching is applied by default and when
tablePattern is not NULL then batching is not applied. In the code it does not
apply batching when tablePattern is not NULL and tableNames is also not NULL
thus causing this issue.
{*}Fix{*}: Apply batching on the basis of tableNames and not tablePattern to
fix this issue
