Just adding a cross-link to
[https://github.com/apache/ozone/pull/1910|https://github.com/apache/ozone/pull/1910]
There is a comment there which explains it in details.
was (Author: elek):
I have seen the proposal on the HDDS-4808, so let me re-share it here:
bq. Recommendation:
bq.
bq. Switch Ozone to use java.util.zip.CRC32 by default.
bq. Switch the non-default CRC32C implementation in Ozone to the Hadoop
pure Java implementation, but use java.util.zip.CRC32C if available.
bq.
But please check the full comment on https://github.com/apache/ozone/pull/1910
