Michael Stack created HBASE-25960:
-------------------------------------
Summary: Build includes unshaded netty .so; clashes w/
downstreamers who would use a different version of netty
Key: HBASE-25960
URL: https://issues.apache.org/jira/browse/HBASE-25960
Project: HBase
Issue Type: Bug
Components: build
Reporter: Michael Stack
A coworker was trying to use hbase client in a fat application that uses a
different netty version to what hbase uses internally. Their app would fail to
launch because it kept bumping into an incompatible netty .so lib. Here are the
unshaded netty .so's we bundle looking at hbase-2.4.1...:
./lib/hbase-shaded-netty-3.4.1.jar has:
{code}
META-INF/native/libnetty_transport_native_epoll_aarch_64.so
META-INF/native/liborg_apache_hbase_thirdparty_netty_transport_native_epoll_x86_64.so
META-INF/native/libnetty_transport_native_epoll_x86_64.so
{code}
(HBASE-25959 should fix the non-relocation of
libnetty_transport_native_epoll_aarch_64).
./lib/shaded-clients/hbase-shaded-client-byo-hadoop-2.4.1.1-apple.jar has the
same three .sos as does
./lib/shaded-clients/hbase-shaded-mapreduce-2.4.1.1-apple.jar
and ./lib/shaded-clients/hbase-shaded-client-2.4.1.1-apple.jar
We even bundle ./lib/netty-all-4.1.17.Final.jar which unsurprisingly has the
netty .sos in it.
Looking at published builds of hbase-thirdparty, I see that these too include
the above trio of .sos... The hbase-shaded-netty includes them in 3.4.1
https://repo1.maven.org/maven2/org/apache/hbase/thirdparty/hbase-shaded-netty/3.4.1/
as does 3.5.0.
I just tried running a build of hbase-thirdparty and it does NOT include the
extras....
META-INF/native/liborg_apache_hbase_thirdparty_netty_transport_native_epoll_aarch_64.so
META-INF/native/liborg_apache_hbase_thirdparty_netty_transport_native_epoll_x86_64.so
(it has the fix for aarch included... when I built)
Here is link to the snapshot I made:
