AiBe Gee commented on HADOOP-11505:
-----------------------------------
Can someone help me with the exact patch revision I should apply for Hadoop
3.1.2 for this reported issue?
http://mirror.netcologne.de/apache.org/hadoop/common/hadoop-3.1.2/hadoop-3.1.2-src.tar.gz
Hadoop 3.1.2 looks to be the only one I'm able to build - going over 50% of the
build until until it hits this bswap ASM issue.
I tried 3.2.0 and 3.3.0 (latest git snapshot) and both are broken:
https://issues.apache.org/jira/browse/HADOOP-16309
https://issues.apache.org/jira/browse/HADOOP-16311
Many thanks in advance!
