[jira] [Created] (ARROW-7100) libjvm not found on ubuntu 19.04 with
java >8
Alexis Mignon created ARROW-7100:
------------------------------------
Summary: libjvm not found on ubuntu 19.04 with java >8
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
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)}}
{{ File "/home/amignon/Projets/Sandbox/bwl_negbin/venv/lib/python3.7/site-packages/pyarrow/hdfs.py", line 40, in __init__}}
{{ self._connect(host, port, user, kerb_ticket, driver, extra_conf)}}
{{ File "pyarrow/io-hdfs.pxi", line 89, in pyarrow.lib.HadoopFileSystem._connect}}
{{ File "pyarrow/error.pxi", line 80, in pyarrow.lib.check_status}}
{{pyarrow.lib.ArrowIOError: Unable to load libjvm}}
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.
