Xiaoyu Yao commented on HDFS-13516: ----------------------------------- RocksDB has Windows support for a while. The issue seems to be a know issue on non-Linux platform like the discussion [here|https://github.com/confluentinc/ksql/issues/1332] {{The resolution is to ensure either one of the directory specified by }}{{java.io.tmpdir}}{{ system property or }}{{ROCKSDB_SHAREDLIB_DIR}}{{ environment variable}}{{ is writable by all users.}} More detailed reason quoted from the discussion link above: "As part of the startup process of RocksDB, it has to extract the C library before it can be used. The location to extract the C library is determined by the {{java.io.tmpdir}} system property or {{ROCKSDB_SHAREDLIB_DIR}} environment variable. If this directory is not writable, then the user will see an error like {{Could not initialize class org.rocksdb.Option."}} > Ozone: TestMetadataStore fails on Windows > ----------------------------------------- > > Key: HDFS-13516 > URL: https://issues.apache.org/jira/browse/HDFS-13516 > Project: Hadoop HDFS > Issue Type: Bug > Reporter: Íñigo Goiri > Priority: Major > > TestMetadataStore fails on Windows with the following error: > java.lang.UnsatisfiedLinkError: > C:\Users\jenkins\AppData\Local\Temp\1\librocksdbjni4617805071197790179.dll: A > dynamic link library (DLL) initialization routine failed > The report can be found > [here|https://builds.apache.org/job/hadoop-trunk-win/449/testReport/org.apache.hadoop.ozone/TestMetadataStore/]. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
