> Key: ARROW-7100
> URL: https://issues.apache.org/jira/browse/ARROW-7100
> Project: Apache Arrow
> Issue Type: Bug
> Components: C++
> Affects Versions: 0.15.1
> Environment: ubuntu 19.04
> Reporter: Alexis Mignon
> Priority: Major
> Labels: pull-request-available
> Fix For: 1.0.0
>
> Time Spent: 10m
> Remaining Estimate: 0h
>
> On ubuntu 19.04, with java-11 installed, the following code raises an error
>
> {{$ python -c "import pyarrow as pa; pa.hdfs.connect()"}}
> {{Traceback (most recent call last):}}
> {{ File "<string>", line 1, in <module>}}
> {{ File
> "/home/amignon/Projets/Sandbox/bwl_negbin/venv/lib/python3.7/site-packages/pyarrow/hdfs.py",
> line 215, in connect}}
> {{ extra_conf=extra_conf)}}

>
> while it works with java-8 installed (even when JAVA_HOME points to java-11).
>
> This seems to be due to a change in the directory structure of java. In
> java-11, libjvm lies in
> /usr/lib/jvm/java-11-openjdk-amd64/lib/server/libjvm.so
> Instead of
> /usr/lib/jvm/java-8-openjdk-amd64/jre/lib/amd64/server/libjvm.so
>
> According to the code of
> [hdfs_internal.cc|https://github.com/apache/arrow/blob/21f610075242c957bf101c073bfee6c3698dfa3d/cpp/src/arrow/io/hdfs_internal.cc#L220]
> the search suffixes on linux are:
>
> {{ }}{{ "/jre/lib/amd64/server", "/lib/amd64/server"}}
> which would explain the problem.
> This is confirmed by adding manually a amd64/server in the java-11 directory.
