My name is Stefano, I am a young software developer.
In these months I am using HBase as database in a Hadoop cluster, to write
data from Apache Spark with scala language.
May I ask you any question for specific information?
*Q1*: there is a way to insert/update a specific cell as latest field into
the same record?
row1 column=CF1:QUAL1, timestamp=1523350296746, value=0.0
row1 column=CF1:QUAL2, timestamp=1523350296746, value=test
row1 column=CF1:QUAL3, timestamp=1523350296746, value=2700
row1 *column=CF2:QUAL4, timestamp=1523350296746, value=01218*
row1 column=CF2:QUAL5, timestamp=1523350296746, value=example
I would like to be sure that the value of the key QUAL4 will be insert as
last field, respect to the other values of the same rowkey (row1).
*Q2*: What is the best way to write in bulk with Spark 2.2? Is the
HBaseContext class available to use the bulkload with Hfiles?
Thank you very much in advance.
