Re: Missing content in phoenix after writing from Spark
Thanks. We topped with the next problem, we do need to do appending. But
current support documentation says only Overwrite mode is available right?
In this case we'll have to resort back to RDD writing, correct?

Re: Missing content in phoenix after writing from Spark
Hi, I am attempting to make connection with Spark but no success so far.
For writing into Phoenix, I am trying this:
tdd.toDF("ID", "COL1", "COL2",
"COL3").write.format("org.apache.phoenix.spark").option("zkUrl",
"zookeper-host-url:2181").option("table",
htablename).mode("overwrite").save()
But getting:
*java.sql.SQLException: ERROR 103 (08004): Unable to establish connection.*
For reading, on the other hand, attempting this:
val hbConf = HBaseConfiguration.create()
val hbaseSitePath = "/etc/hbase/conf/hbase-site.xml"
hbConf.addResource(new Path(hbaseSitePath))
spark.sqlContext.phoenixTableAsDataFrame("VISTA_409X68", Array("ID"), conf
= hbConf)
Gets me
*java.lang.NoClassDefFoundError: Could not initialize class
org.apache.phoenix.query.QueryServicesOptions*
I have added phoenix-queryserver-5.0.0-HBase-2.0.jar and
phoenix-queryserver-client-5.0.0-HBase-2.0.jar
Any thoughts? I have an hbase-site.xml file with more configuration but not
sure how to get it to be read in the saving instance.
Thanks

Re: Missing content in phoenix after writing from Spark
Thank you Josh! That was helpful. Indeed, there was a salt bucket on the
table, and the key-column now shows correctly.
However, the problem still persists in that the rest of the columns show as
completely empty on Phoenix (appear correctly on Hbase). We'll be looking
into this but if you have any further advice, appreciated.

Missing content in phoenix after writing from Spark
Hi all,
We're trying to write tables with all string columns from spark.
We are not using the Spark Connector, instead we are directly writing byte
arrays from RDDs.
The process works fine, and Hbase receives the data correctly, and content
is consistent.
However reading the table from Phoenix, we notice the first character of
strings are missing. This sounds like it's a byte encoding issue, but we're
at loss. We're using PVarchar to generate bytes.
Here's the snippet of code creating the RDD:
val tdd = pdd.flatMap(x => {
val rowKey = PVarchar.INSTANCE.toBytes(x._1)
for(i <- 0 until cols.length) yield {
other stuff for other columns ...
...
(rowKey, (column1, column2, column3))
}
})
...
We then create the following output to be written down in Hbase
val output = tdd.map(x => {
val rowKeyByte: Array[Byte] = x._1
val immutableRowKey = new ImmutableBytesWritable(rowKeyByte)
val kv = new KeyValue(rowKeyByte,
PVarchar.INSTANCE.toBytes(column1),
PVarchar.INSTANCE.toBytes(column2),
PVarchar.INSTANCE.toBytes(column3)
)
(immutableRowKey, kv)
})
By the way, we are using *KryoSerializer* in order to be able to serialize
all classes necessary for Hbase (KeyValue, BytesWritable, etc).
The key of this table is the one missing data when queried from Phoenix. So
we guess something is wrong with the byte ser.
Any ideas? Appreciated!
Saif
