Dan LaRocque created HBASE-10494:
------------------------------------
Summary: hadoop2 class reference in Maven Central's
hbase-client-0.96.1.1-hadoop1
Key: HBASE-10494
URL: https://issues.apache.org/jira/browse/HBASE-10494
Project: HBase
Issue Type: Bug
Affects Versions: 0.96.1.1
Environment: Only affects jar on Maven Central. Jar in the hadoop1
tarball download is not affected.
Reporter: Dan LaRocque
Priority: Minor
RpcClient$Connection.class as shipped in the hbase-client-0.96.1.1-hadoop1 jar
on Maven Central contains references to
org.apache.hadoop.net.SocketInputWrapper. I think this class does not exist in
hadoop1 because a classfile search of central yields hits only on 2.0 and 0.23.
There may be other references. I only know about this one because it was
killing my HRegionServer early with this exception:

I first stumbled over this while developing an app managed by Maven that
depends on hbase-client, but then reproduced it by extracting the hadoop1
tarball and replacing the client jar with the same-named one from Maven Central.
I think this is not the same as HBASE-7269, although the stacktrace is similar.
Here's a disassembler grep on the Maven Central copy showing some references:
{noformat}
# From the root of an extracted hbase-client-0.96.1.1-hadoop1 jar downloaded
from Maven Central
client-maven$ javap -verbose
'org/apache/hadoop/hbase/ipc/RpcClient$Connection.class' | grep
SocketInputWrapper
#198 = Methodref #744.#818 //
org/apache/hadoop/net/NetUtils.getInputStream:(Ljava/net/Socket;)Lorg/apache/hadoop/net/SocketInputWrapper;
#818 = NameAndType #1115:#1159 //
getInputStream:(Ljava/net/Socket;)Lorg/apache/hadoop/net/SocketInputWrapper;
#1159 = Utf8
(Ljava/net/Socket;)Lorg/apache/hadoop/net/SocketInputWrapper;
180: invokestatic #198 // Method
org/apache/hadoop/net/NetUtils.getInputStream:(Ljava/net/Socket;)Lorg/apache/hadoop/net/SocketInputWrapper;
{noformat}
Here's the same grep on the tarball's copy. No references.
{noformat}
# Same as above, but using jar from the download tarball for hadoop1
client-tarball$ javap -verbose
'org/apache/hadoop/hbase/ipc/RpcClient$Connection.class' | grep
SocketInputWrapper
client-tarball$
{noformat}
What do you think?
