Hi,
Under Hbase Home directory I get
hduser@rhes75: /data6/hduser/hbase-2.0.0> find ./ -name '*.jar' -print
-exec jar tf {} \; | grep -E "\.jar$|StreamCapabilities" | grep -B 1
StreamCapabilities
./lib/phoenix-5.0.0-alpha-HBase-2.0-client.jar
org/apache/hadoop/hbase/util/CommonFSUtils$StreamCapabilities.class
org/apache/hadoop/fs/StreamCapabilities.class
org/apache/hadoop/fs/StreamCapabilities$StreamCapability.class
--
./lib/hbase-common-2.0.0.jar
org/apache/hadoop/hbase/util/CommonFSUtils$StreamCapabilities.class
for Hadoop home directory I get nothing
hduser@rhes75: /home/hduser/hadoop-2.7.3> find ./ -name '*.jar' -print
-exec jar tf {} \; | grep -E "\.jar$|StreamCapabilities" | grep -B 1
StreamCapabilities
