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."}}
