Can't connect to the remote hbase with gohbase however works smoothly with happybase(Python Client)

[keyunjie96]

Hi, we tried to connect the remote hbase server from a Ubuntu Server with the following gohbase code.

package main

import (
	"context"
	"fmt"

	"github.com/tsuna/gohbase"
	"github.com/tsuna/gohbase/hrpc"
)

func main() {
	host := "OUR_HOST_DNS"
	HBase := gohbase.NewClient(host, gohbase.FlushInterval(0))
	family := map[string][]string{"intermediate_list": {"intermediate_content"}}
	request, err1 := hrpc.NewGetStr(
		context.Background(),
		"intermediates",
		"ee1560527322",
		hrpc.Families(family))
	if err1 != nil {
		fmt.Println("Getting Intermediate Creating Request Error:", err1)
	}
	fmt.Println("GetStr Done")
	_, err2 := HBase.Get(request)
	fmt.Println("Get Done")
	if err2 != nil {
		fmt.Println("Getting Intermediate Scanning Error:", err2)
	}
}

But it failed. If we put the above gohbase code on the remote master node, then it can run without the following errors.

ERRO[0040] failed looking up region                      backoff=16ms err="context deadline exceeded" key="\"ee1560527322\"" table="\"intermediates\""
ERRO[0070] failed looking up region                      backoff=32ms err="context deadline exceeded" key="\"ee1560527322\"" table="\"intermediates\""
ERRO[0100] failed looking up region                      backoff=64ms err="context deadline exceeded" key="\"ee1560527322\"" table="\"intermediates\""

However, we can connect to the remote hbase server from the Ubuntu Server through happybase with Python using the following code. We get exactly what we want.

import happybase
connection = happybase.Connection("OUR_HOST_DNS")
table = connection.table("intermediates")
row = table.row(b'ee1560527322')
print(row)

Because we can run it with Python and barely opened 0-65536 ports for any IP address, I think the reason can't be the network or hbase configuration. So I am wondering if there is anything we have missed in our gohbase client... Any words can help. Thanks in advance!

I have same problem with you, just now, i solve it. I solve it with following methods. """you can turn on the logrus.debuglevel to see the problem."""

Add the hbase cluster ip and host info to /etc/hosts. Then you can use correctly!

eg. My hbase cluster has 2 masters and 3 slaves , add belows to /etc/hosts 196.1.1.1 master1 196.1.1.2 master2 196.1.2.1 core1 196.1.2.2 core2 196.1.2.3 core3
