Re: Impala critical bug in CDH 5.14.0

https://issues.apache.org/jira/browse/IMPALA-6882 is easy to rule out since it only occurs on > 5 year old processors.

Re: Impala critical bug in CDH 5.14.0

Thank you Chris for providing more information. It looks like it crashed in the code that writes Parquet files (HdfsParquetTableWriter::ColumnWriter<impala::StringValue>::ProcessValue). However, your query should not write any data: "SELECT a.topLevelField, b.priceFromNestedField FROM db.table a LEFT JOIN a.nestedField b"

 

I also noticed that the stack looks like it has been overwritten by something.

 

I don't recall any recent issues in that method and will have a look at the code to see if I can spot anything obvious.

 

In the meantime, can you double check that this query caused the crash and no other query was running?

 

Thanks, Lars

Re: Impala critical bug in CDH 5.14.0

Hi Lars,

Yes it was this query as if it was run many time it would always cause the crash.

I'm upgrading the cluster to 5.14.2 this afternoon to see if that resolves the issue. I'll update you later today (uk time) to let you know how it goes.

Lars - Tim,

This issue has been resolved by upgrading to version 5.14.2.  Thanks for all your assistance.

Cheers,
Chris

Re: Impala critical bug in CDH 5.14.0

 

The reason you were seeing HdfsParquetTableWriter::ColumnWriter is that I was testing the bug using the syntax:

 

CREATE TABLE db.newTable STORED AS PARQUET AS

SELECT a.topLevelField, b.priceFromNestedField FROM db.table a LEFT JOIN a.nestedField 

 

This was purely to force the bug to occur - if you just did the SELECT in Hue it would often succeed because it only brings back the first 100 rows - to consistently trigger the crash I had to make Impala read from both Parquet files. No other query was running at the time.

 

Anyway, as Chris says, the bug appears to be fixed in 5.14.2. The job which originally consistently triggered the crash has now been running unchanged over the same source data for 20 hours without hitch.

 

Thanks for your help

Matt
