Description
Hey folks 
I'm hitting the 'signature not found' NPE precondition in ArrowFlightMetaImpl.execute when I prepare a DML statement and call executeUpdate (the prepare step seems to work fine):
Preconditions.java: 801 cfjd.org.apache.arrow.util.Preconditions/checkNotNull
ArrowFlightMetaImpl.java: 86 org.apache.arrow.driver.jdbc.ArrowFlightMetaImpl/execute
ArrowFlightMetaImpl.java: 96 org.apache.arrow.driver.jdbc.ArrowFlightMetaImpl/execute
AvaticaConnection.java: 548 cfjd.org.apache.calcite.avatica.AvaticaConnection/executeQueryInternal
AvaticaPreparedStatement.java: 152 cfjd.org.apache.calcite.avatica.AvaticaPreparedStatement/executeLargeUpdate
AvaticaPreparedStatement.java: 147 cfjd.org.apache.calcite.avatica.AvaticaPreparedStatement/executeUpdate
It seems that this will always be null in this situation because AvaticaPreparedStatement.executeLargeUpdate calls executeQueryInternal with a null signature, regardless of the signature in the prepared statement itself (which is non-null)?
Otherwise, enjoying playing with FlightSQL so far - thanks!
James
