what are hbase releated jars used for set in pom

[WangYQ]

when build oozie, we need to set some versions:
     <hadoop.version>2.6.0</hadoop.version>
        <hadoop.majorversion>2</hadoop.majorversion>
        
<hadooplib.version>hadoop-${hadoop.majorversion}-${project.version}</hadooplib.version>
        
<oozie.hadoop-utils.version>hadoop-${hadoop.majorversion}-${project.version}</oozie.hadoop-utils.version>
        <hbase.version>0.98.10-hadoop2</hbase.version>
  <hive.version>1.2.1</hive.version>
         <hive.jline.version>2.12</hive.jline.version>
         <hive.classifier>core</hive.classifier>
         <pig.version>0.16.0</pig.version>
         <pig.classifier></pig.classifier>
         <sqoop.version>1.4.5</sqoop.version>
         <spark.version>1.5.1</spark.version>
         <spark.streaming.kafka.version>1.5.1</spark.streaming.kafka.version>
         <spark.bagel.version>1.5.1</spark.bagel.version>
         <spark.guava.version>14.0.1</spark.guava.version>
         <spark.scala.binary.version>2.10</spark.scala.binary.version>
         <sqoop.classifier>hadoop100</sqoop.classifier>
         <streaming.version>${hadoop.version}</streaming.version>
         <distcp.version>${hadoop.version}</distcp.version>
         <hadoop.auth.version>${hadoop.version}</hadoop.auth.version>




for spark ,sqoop, distcp,  we will put these jars in share lib
but for hbase jars,  what are these jars used for?   can we delete the pom conf 
for  hbase
