This directory contains the hdfs extensions needed to make rocksdb store
|
|
files in HDFS.
|
|
|
|
The hdfs.h file is copied from the Apache Hadoop 1.0 source code.
|
|
It defines the libhdfs library
|
|
(http://hadoop.apache.org/common/docs/r0.20.2/libhdfs.html) to access
|
|
data in HDFS. The libhdfs.a is copied from the Apache Hadoop 1.0 build.
|
|
It implements the API defined in hdfs.h. If your hadoop cluster is running
|
|
a different hadoop release, then install these two files manually from your
|
|
hadoop distribution and then recompile rocksdb.
|
|
|
|
The env_hdfs.h file defines the rocksdb objects that are needed to talk to an
|
|
underlying filesystem.
|
|
|
|
If you want to compile rocksdb with hdfs support, please set the following
|
|
enviroment variables appropriately:
|
|
USE_HDFS=1
|
|
JAVA_HOME=/usr/local/jdk-6u22-64
|
|
LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/jdk-6u22-64/jre/lib/amd64/server:/usr/local/jdk-6u22-64/jre/lib/amd64/:./snappy/libs
|
|
make clean all db_bench
|
|
|
|
To run dbbench,
|
|
set CLASSPATH to include your hadoop distribution
|
|
db_bench --hdfs="hdfs://hbaseudbperf001.snc1.facebook.com:9000"
