Make sure that the nosuid flag isn't set on the /var (or /var/lib) mount point in /etc/fstab.   Since this release the container-executor has now moved to /var/lib/yarn-ce, which for many users will be on a different mount that it was previously (perhaps /opt or /usr).   This should probably be in the release notes for v5.16, as it isn't clear that the default location of container-executor has moved, and potential implications this will have.   Matt   ...

  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     ... View more
