David Li commented on ARROW-18294: ---------------------------------- Thanks for reporting. Happy to see that you're giving Flight SQL a try, any feedback there would be appreciated. I'll see if I can get this replicated and fixed quickly. We're considering a 10.0.1 release, so it would be nice to include a fix for this. > [Java][FlightRPC] 'Signature not found' calling `executeUpdate` on FlightSQL > prepared statement > ----------------------------------------------------------------------------------------------- > > Key: ARROW-18294 > URL: https://issues.apache.org/jira/browse/ARROW-18294 > Project: Apache Arrow > Issue Type: Bug > Components: FlightRPC, Java > Affects Versions: 10.0.0 > Reporter: James Henderson > Assignee: David Li > Priority: Major > > 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): > {code} > 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 > {code} > 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 -- This message was sent by Atlassian Jira (v8.20.10#820010)
