[jira] [Updated] (HUDI-2812) Upgrade Parquet to 1.12
[ https://issues.apache.org/jira/browse/HUDI-2812?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Alexey Kudinkin updated HUDI-2812:
----------------------------------
Description:
Current version of Apache Parquet is from 2 years old and contains at least one known race-condition that might be compromising correctness of the \{{DateType}}:
Current version of 1.10 (and seems like 1.11 as well) contains {{DateStringifier class that uses *static shared* {{SimpleDataFormat}}}} object which is known to be NOT thread-safe.
Therefore any access to that object (for example upon serialization) exposes use to RCs.
