due to netty shading
Shubham Chaurasia created HIVE-24138:
----------------------------------------
Summary: Llap external client flow is broken due to netty shading
Key: HIVE-24138
URL: https://issues.apache.org/jira/browse/HIVE-24138
Project: Hive
Issue Type: Bug
Components: llap
Reporter: Shubham Chaurasia
We shaded netty in hive-exec in - https://issues.apache.org/jira/browse/HIVE-23073
This breaks LLAP external client flow on LLAP daemon side -

{code}
Arrow method signature mismatch mainly happens due to the fact that arrow contains some classes which are packaged under {{io.netty.buffer.*}} -
{code}
io.netty.buffer.ArrowBuf
io.netty.buffer.ExpandableByteBuf
io.netty.buffer.LargeBuffer
io.netty.buffer.MutableWrappedByteBuf
io.netty.buffer.PooledByteBufAllocatorL
io.netty.buffer.UnsafeDirectLittleEndian
{code}
Since we have relocated netty, these classes have also been relocated to {{org.apache.hive.io.netty.buffer.*}}
