Hi. I'm trying to connect to HBase from Spark using this connector https://github.com/hortonworks-spark/shc This is my code: def catalog = s"""{
|"table":{"namespace":"default", "name":"terminals"},
|"rowkey":"key",
|"columns":{
|"col0":{"cf":"rowkey", "col":"key", "type":"string"},
|"col1":{"cf":"tinfo", "col":"status", "type":"int"},
|"col2":{"cf":"tinfo", "col":"latitude", "type":"double"},
|"col2":{"cf":"tinfo", "col":"longitude", "type":"double"}
|}
|}""".stripMargin
def withCatalog(cat: String): DataFrame = {
sqlContext
.read
.options(Map(HBaseTableCatalog.tableCatalog->cat))
.format("org.apache.spark.sql.execution.datasources.hbase")
.load()
}
val df = withCatalog(catalog)
df.show()
val dfFilter = df.filter($"col0".isin("1212121"))
parsed.join(dfFilter, parsed("terminal_id") === dfFilter("col0")).show() but when I try to execute with spark-submit: spark-submit --class com.location.userTransactionMain --master local[*] --files /etc/hbase/conf/hbase-site.xml userTransactionAppScala-assembly-1.0.jar It returns an error:
Exception in thread "main" java.lang.NullPointerException: Please define 'tableCoder' in your catalog. If there is an Avro records/schema in your catalog, please explicitly define 'coder' in its corresponding column.

Hi. I answer myself. With libhdfs is possible write to HDFS from UDF. I've tested it and it works fine!!!

Hi Is it possible write a buffer into HDFS from UDF Impala (C++ or Java)? So I'd like simulate UDTF in Impala. First call to UDF to write output in HDFS. Later, another query reads these data from HDFS. If it is possible, it will be with libhdfs. How can I install libhdfs-dev in debian wheezy? Thanks!!! Regards.

Yes. Use Impala or Hive to convert to Parquet stream from Flume is a good option, although it would be nice to have it natively. Thanks!!!! Miguel Angel.
