Installation (pip)

pip3 install hbase-driver

Get Started

from hbasedriver.client import Client
from hbasedriver.operations import Put, Get, Scan
from hbasedriver.exceptions.RemoteException import TableExistsException

# lets say your hbase instance runs on 127.0.0.1 (zk quorum address)
client = Client(["127.0.0.1"])
try:
    client.create_table("", "mytable", ['cf1', 'cf2'])
except TableExistsException:
    pass
table = client.get_table("", "mytable")
table.put(Put(b'row1').add_column(b'cf1', b'qf', b'666'))
table.put(Put(b'row1').add_column(b'cf1', b'qf2', b'999'))
table.put(Put(b'row1').add_column(b'cf2', b'qf', b'777'))
table.put(Put(b'row2').add_column(b'cf1', b'qf123', b'777'))
result = table.get(Get(b"row1").add_column(b'cf1', b'qf'))
print("get result =", result)
assert b'666' == result.get(b'cf1', b'qf')

scan_result = table.scan(Scan(b"row1").add_family(b'cf1'))
# retrieve all results from the iterator.
scan_result = list(scan_result)
print("scan result below:")
for row in scan_result:
    print(row)

Master (metadata) operations

from hbasedriver.client import Client

client = Client(["127.0.0.1"])
# describe table
res = client.master.describe_table(None, "mytable")
print(res)
# table_name {
#     namespace: "default"
#     qualifier: "test_table_master"
#   }
#   attributes {
#     first: "IS_META"
#     second: "false"
#   }
#   attributes {
#     first: "hbase.store.file-tracker.impl"
#     second: "DEFAULT"
#   }
#   column_families {
#     name: "cf1"
#     attributes {
#       first: "INDEX_BLOCK_ENCODING"
#       second: "NONE"
#     }
# ..........
