Doris deploy problem and create table failed issue.

[13671653088]

hi all,
I deployed a doris cluster with one fe and three be, version 0.12.
fe and be 10002 deployed on one server,and be 10003,10004 deploy on the other two servers;
show backends can't get the disk infomations from 10003,10004.

I found the follow warning in log/be.WARING.log.xxxx, and have no idea

W0313 13:48:47.399816 4857 task_worker_pool.cpp:1186] finish report olap table state failed. status:-1, master host:10.80.220.42, port:9020

And when i tried to create table , wrong again

CREATE TABLE example_db.table_hash ( k1 TINYINT, k2 DECIMAL(10, 2) DEFAULT "10.5", v1 CHAR(10) REPLACE, v2 INT SUM ) ENGINE=olap AGGREGATE KEY(k1, k2) COMMENT "my first doris table" DISTRIBUTED BY HASH(k1) BUCKETS 32 PROPERTIES ("storage_type"="column");

ERROR 1064 (HY000): errCode = 2, detailMessage = Failed to create partition[table_hash]. Timeout. Unfinished mark: 10003=10178, 10003=10242, 10003=10182

I found the follow warning in fe/log/fe.warn.log

This problem has been solved.
The problem caused by network block.
We need ensure that be can access fe 9030.

some suggestion:

1. check the firewall status, or reset the firewall with "sudo iptables -F"
2. check the Listening port with "netstat -lnpt"
3. if you are using cloud server, check the server secure setting.
