Turn on DEBUG log4j client side (beware of chatty ZK logging) and see if
there's something obvious from when the EXPLAIN is slow.

We have an issue with our production environment - from time to time we notice
a significant performance degradation for some queries. The strange thing is
that the EXPLAIN operator for these queries takes the same time as queries
execution (5 minutes or more). So, I guess, the issue is relat

Hi,
Is the ODBC driver from Hortonworks the only way to access Phoenix from .NET
code now?
The problem is that driver has some critical limitations - it seems, driver
doesn't support Namespace Mapping (it couldn't be able to connect to Phoenix if
phoenix.schema.isNamespaceMappingEnabled=true)
rsion of Phoenix and HBase
you’re using. Your example should work as expected barring declaration of
the table as immutable or COL2 being part of the primary key.
Thanks,

Hi,
Could you please clarify, how I can set a value to NULL?
After upsert into temp.table (ROWKEY, COL1, COL2) values (100, "ABC", null);
the value of COL2 still has a previous value (COL1 has "ABC" as expected).
Or there is only one way - to set STORE_NULLS = true?
Thanks,
Stepan.

You may actually find that using the built-in UPSERT SELECT logic may

We use Spark 2.2.1; hbase 1.1.2, Phonix 4.13, Hive 2.1.1
So it seems that Spark + Phoenix led great performance degradation. Any
thoughts?
