Re: Phoenix Connection Lost on Map Reduce Job Intermittently

That's not enough context for us to diagnose why your job is failing, but this stack trace exists only in Hadoop code. Given that, I would have to assume it's a bug in Hadoop 3.0.0. There are many newer versions of Hadoop and I would suggest you use one of the latest releases of Hadoop 3,

Phoenix Connection Lost on Map Reduce Job Intermittently

Re: Phoenix connection issue

If you are not using Kerberos authentication, then you need to figure out how your DNS names are resolving for your VM. A SocketTimeoutException means that your client could not open an socket to that host:port which was specified. Likely, this is something you need to figure out with your VM.

Re: Phoenix connection issue

(-to: dev@phoenix, +bcc: dev@phoenix, +to: user@phoenix) I've taken the liberty of moving this over to the user list. Typically, such an exception is related to Kerberos authentication, when the HBase service denies in an incoming, non-authenticated client. However, since you're running

Can you set log4j to DEBUG? That will give you a hint about what's going on the server. On Thu, 14 Jun 2018, 18:40 Susheel Kumar Gadalay, wrote: > Can someone please help me to resolve this. > > Thanks > Susheel Kumar > > On Tuesday, June 12, 2018, Susheel Kumar Gadalay > wrote: > > Hi, > > >

Phoenix Connection

After we did upgrade to 4.10 on a CDH 5.10, we do see too many ZK connections (increased the max connections form 60->300->1000), but the problem still exist. Are there any known issues? Phoenix connection leak? Appreciate your time.

Looking for some recommendation around managing connections. We have a REST service using Phoenix + Hbase and are looking to support a high volume of request and it's my understanding from previous posting the phoenix jdbc connections all share the same underlying HBase connection regardless the

Josh, One step worth trying would be is to register the PhoenixDriver instance and see if that helps. Something like this: DriverManager.registerDriver(PhoenixDriver.INSTANCE) Connection con = DriverManager.getConnection("jdbc:phoenix:localhost:2181”) - Samarth On Wed, Dec 2, 2015 at 3:41 PM,

Phoenix connection pooling in a multi-tenant environment‏

Phoenix is an embedded driver and it automatically manages connection pooling. In case of multi-tenancy, tenant-specific connections are created by specifying tenantId property in JDBC. Does phoenix still automatically handle connection pooling, if I create multiple connections each with

Re: Phoenix Connection Timeout

Hey Nick, Sergey, Thanks for taking a look. It was just going through a really really long HBase connection retry loop (20+ minutes!). However, even setting the retries and delays to 0 in the hbase-site.xml, the connection still takes about 3 minutes to timeout. Now I'm wondering if there is a

It definitely hangs forever from what I experienced. It also does not allow to exit from it and only killing terminal session helps. On Fri, May 22, 2015 at 6:13 PM, Nick Dimiduk ndimi...@gmail.com wrote: Hi Alex, It's probably not hanging forever, but going through the -- very long by

Re: Phoenix connection never returns

Hi Russell, Just a naive question, Are you able to connect to HBase via HBase shell or any other HBase client from that node? I have seen this kind of behavior when the client does not have the HBase cluster conf in its classpath. Thanks, Anil Gupta On Wed, Jun 25, 2014 at 10:51 PM, Russell
