> This is specifically for the IOP to HDP migration. We started with an IOP 4.2.5 cluster where HDFS had "com.hadoop.compression.lzo" as part of the core-site/io.compression.codecs property value.  After Ambari upgrade (build 2.5.2-155), we couldn't restart HDFS, where it failed with the following error (bold/italic for the error line)
> IOP 4.2.5 lzo package is hadoop-lzo-0.5.1-2.x86_64.rpm, which doesn't fit the naming convention Ambari 2.5.2 uses (seems to be coming from HDP 2.3 stack via inheritance). It's also puzzling why the inheritance as this was right after Ambari upgrade where the stack was still IOP 4.2.5 stack that extends common services directly.
