We tend to setup our hbase test tables by shell scripts. Hence we have to execute multiple puts and deletes in a row. When you add an hbase shell [command] for each single operation you will have to wait a long time until all commands are processed. A more performant proceeding is to put all commands in one single <<EOF … EOF construct which basically allows to pass a multi line parameter to the shell.
hbase shell <<EOF
put 'shared:ITEMS','item0001','c:value','1.0'
put 'shared:ITEMS','item0002','c:value','2.0'
put 'shared:ITEMS','item0003','c:value','3.0'
put 'shared:ITEMS','item0004','c:value','4.0'
put 'shared:ITEMS','item0005','c:value','5.0'
put 'shared:ITEMS','item0006','c:value','6.0'
EOF |
Doing so hbase will only start one shell instead of starting an instance for each single command.
