László Bodor updated TEZ-4376:
------------------------------
Description:
When I try to start yarn nodemanager with tez shufflehandler configured, I get
this:
{code:java}
java.lang.NoClassDefFoundError:

{code}
this is because in netty 4, EmptyArrays class - which is originally referred to
by DefaultChannelId, here the stacktrace shows that I simply copied it to
ShuffleHandler code to insert some logging - refers to X509Certificate
I tried to add javax.security exclude as:
{code:java}
<relocation>
<pattern>javax</pattern>
<shadedPattern>org.apache.tez.shaded.$0</shadedPattern>
<excludes>
<exclude>javax.crypto.*</exclude>
<exclude>javax.security.*</exclude> <!-- HERE -->
</excludes>
</relocation>
{code}
but it didn't work, not sure why
*when I completely removed javax relocation, it started to work*
I'm tempted to make javax.security exclusion work, but first I need to
understand why javax relocation is needed at all
is there a chance that we want to package a custom javax to be used instead of
what is provided on nodemanager's classpath?
