> Key: IMPALA-12043
> URL: https://issues.apache.org/jira/browse/IMPALA-12043
> Project: IMPALA
> Issue Type: Bug
> Components: Catalog
> Affects Versions: Impala 4.2.0
> Reporter: Michael Smith
> Assignee: Riza Suminto
> Priority: Major
>
> Large results from something like {{COMPUTE INCREMENTAL STATS}} can result in a warning like
> {code}
> W0402 18:19:03.456277 250159 CatalogdMetaProvider.java:1235] 774b8a34875b106f:71548b8b00000000] Unable to deserialize updated catalog info. Skipping cache invalidation which may result in stale metadata being used at this coordinator.
> Java exception follows:
> org.apache.thrift.transport.TTransportException: MaxMessageSize reached
> at org.apache.thrift.transport.TEndpointTransport.resetConsumedMessageSize(TEndpointTransport.java:58)
> {code}
> This happens when https://github.com/apache/impala/blob/master/fe/src/main/java/org/apache/impala/catalog/local/CatalogdMetaProvider.java#L1231 receives a buffer through the JNI from NativeGetNextCatalogObjectUpdate that exceeds 100MB. [TByteBuffer|https://www.javadoc.io/doc/org.apache.thrift/libthrift/0.16.0/org/apache/thrift/transport/TByteBuffer.html] inherits from TEndpointTransport, which in Thrift 0.16.0 adds a MaxMessageSize limit. TMemoryBuffer adds a constructor that allows passing in a TConfiguration object to customize the limit, which we make use of in IMPALA-11669, but TByteBuffer does not provide a similar interface (THRIFT-5696) and was overlooked.
