Hi,
I have an Hbase table 'trading:MARKETDATAHBASEBATCH'
Kafka delivers topic rows into flume.
This is a typical json row
f2d7174e-6299-49a7-9e87-0d66c248e66b
{"rowkey":"f2d7174e-6299-49a7-9e87-0d66c248e66b","ticker":"BP",
"timeissued":"2020-02-14T08:54:13", "price":573.25}
The rowkey is UUID
The json.conf for Flume is as follows:
# Describing/Configuring the sink
JsonAgent.channels.hdfs-channel-1.type = memory
JsonAgent.channels.hdfs-channel-1.capacity = 300
JsonAgent.channels.hdfs-channel-1.transactionCapacity = 100
JsonAgent.sinks.Hbase-sink.type = org.apache.flume.sink.hbase.HBaseSink
JsonAgent.sinks.Hbase-sink.channel =hdfs-channel-1
JsonAgent.sinks.Hbase-sink.table =trading:MARKETDATAHBASEBATCH
JsonAgent.sinks.Hbase-sink.columnFamily=PRICE_INFO
JsonAgent.sinks.Hbase-sink.serializer
=org.apache.flume.sink.hbase.SimpleHbaseEventSerializer
##JsonAgent.sinks.Hbase-sink.serializer.regex =(.+),(.+),(.+),(.+)
agent1.sinks.sink1.serializer.regex
=[a-zA-Z0-9]*^C[a-zA-Z0-9]*^C[a-zA-Z0-9]*
JsonAgent.sinks.Hbase-sink.serializer.rowKeyIndex = ROW_KEY
JsonAgent.sinks.Hbase-sink.serializer.colNames
=ROW_KEY,ticker,timeissued,price
JsonAgent.sinks.Hbase-sink.serializer.regexIgnoreCase = true
JsonAgent.sinks.Hbase-sink.batchSize =100
The problem is that the rows are inserted as follows
defaultff90d8d3-d8c5-40ff-bc37-6ee1544988c1
column=PRICE_INFO:pCol, timestamp=1581670394182,
value={"rowkey":"a7464cf4-42a1-40b8-a597-a41fbc3b847f","ticker":"MRW",
"timeissued":"2020-02-14T09:03:46", "price":317.13}
So it creates a default rowkey value
"defaultff90d8d3-d8c5-40ff-bc37-6ee1544988c1" followed by json values all
in value column
Ideally I would like something similar to below:
hbase(main):085:0> put 'trading:MARKETDATAHBASEBATCH',
"8b97d3b9-e87b-4f21-9879-b43c4dcccb37", 'PRICE_INFO:rowkey',
"8b97d3b9-e87b-4f21-9879-b43c4dcccb37"
hbase(main):086:0> put 'trading:MARKETDATAHBASEBATCH',
"8b97d3b9-e87b-4f21-9879-b43c4dcccb37", 'PRICE_INFO:ticker', "ORCL"
hbase(main):087:0> put 'trading:MARKETDATAHBASEBATCH',
"8b97d3b9-e87b-4f21-9879-b43c4dcccb37", 'PRICE_INFO:timeissued',
"2020-02-14T09:57:32"
hbase(main):001:0> put 'trading:MARKETDATAHBASEBATCH',
"8b97d3b9-e87b-4f21-9879-b43c4dcccb37", 'PRICE_INFO:price' ,22.12
hbase(main):002:0> get 'trading:MARKETDATAHBASEBATCH',
"8b97d3b9-e87b-4f21-9879-b43c4dcccb37"
COLUMN CELL
PRICE_INFO:price
timestamp=1581676221846, value=22.12
PRICE_INFO:rowkey
timestamp=1581675986932, value=8b97d3b9-e87b-4f21-9879-b43c4dcccb37
PRICE_INFO:ticker
timestamp=1581676103443, value=ORCL
PRICE_INFO:timeissued
timestamp=1581676168656, value=2020-02-14T09:57:32
Any advice would be appreciated.
Thanks,
Mich
