When I'm starting presto as this, it was started but
sys2079#sys2079:~/Music/presto-server-0.149$ sudo bin/launcher start
Started as 10672
After that i tried to lunch the presto then I'm getting error like this
sys2079#sys2079:~/presto-server-0.149$ sudo bin/launcher run
Unrecognized VM option 'G1HeapRegionSize = 32M'
Did you mean 'G1HeapRegionSize='?
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.
WHAT I HAVE TO DO ????
try changing the RAM in your /etc/config.properties file
coordinator=true
node-scheduler.include-coordinator=true
http-server.http.port=8080
query.max-memory=5GB
query.max-memory-per-node=1GB
discovery-server.enabled=true
discovery.uri=http://<your IP or *Localhost*>:8080
Hope this helps
The problem is in your jvm.config file inside presto. You should write your JVM option as: G1HeapRegionSize=32M instead of G1HeapRegionSize = 32M

My python version is 3.7, and after I ran pip3 install happybase, I started the command hbase thrift start and tried to write a brief .py file as following:
import happybase
connection = happybase.Connection('master')
table = connection.table('jmlr') #'jmlr' is a table in hbase
for i in table.scan():
print(i)
table.put('001', {'title':'dasds'}) #error here
connection.close()
When it's about to run table.put(), it reported such an error:
thriftpy2.transport.base.TTransportException: TTransportException(type=4, message='TSocket read 0 bytes')
And at the same time, the thrift reported an error:
ERROR [thrift-worker-1] thrift.TBoundedThreadPoolServer: Error occurred during processing of message. java.lang.IllegalArgumentException: Invalid famAndQf provided.
But just now I ran this python file again, it gave me a different error in thrift:
thrift.TBoundedThreadPoolServer: Thrift error occurred during processing of message.
org.apache.thrift.protocol.TProtocolException: Bad version in readMessageBegin
I have tried to add parameters like protocol='compact', transport='framed', but this didn't work, even the table.scan() failed.
Everything in the hbase shell is OK, so I can't figure out what went wrong, I'm about to collapse.
I ran into the same issue and found this sollution. You need to add even empty Column Qualifier ( ':' symbol as delimiter between Column Family and Column Qualifier) into put() method:
table.put('001:', {'title':'dasds'})
Also, you have a different error message after second run of script because thrift server is already failed.
I hope it will help you.
I am adding a new node to existing single node in vertica, I'm getting this error
Error: scp failed. Tried to retrieve '/opt/vertica/log/verify-latest.xml' from '103.++.++.++'
System prerequisites failed. Threshold = WARN
Hint: Fix above failures or use --failure-threshold
Installation FAILED with errors.
What I have to do ? Need help :(
yeah I got the answer
Edit /opt/vertica/share/eggs/vertica/network/scp.py file with add where scp -P < Port >, you have to menstion your port there.
Hi I have installed Kamalio it start first time but when I stop and start it again it gives sctp_core_destroy(): SCTP API not initialized . I have already installed sctp module.
yyerror_at(): parse error in config file /etc/kamailio/kamailio.cfg
load_module(): could not find module <db_mysql> in </usr/lib/kamailio/modules>
[sctp_core.c:53]: sctp_core_destroy(): SCTP API not initialized
From the log it is obvious that you have successfully compiled & installed SCTP module, however it could NOT be initialized.
Note that is error could must often than not be as a result of other errors in your cfg file.
Few tips:
Can you run kamailio -c and to be sure there is NO error in your cfg.
Found error? use this command to monitor what the exact issue is. Run from a different terminal tail -fn200 /var/log/syslog
On the second terminal try restarting you Kamalio server sudo service kamalio restart
Revisit terminal 1 and look out for the first line with CRITICAL output like the one below CRITICAL: <core> [core/cfg.y:3413]: yyerror_at(): parse error in config file /usr/local/etc/kamailio/kamailio.cfg, line 366, column 41: syntax error
Line 366 mostly is the issue so visit that file at that line (366) to fix the proble
sudo nano +366 /usr/local/etc/kamailio/kamailio.cfg
Let me know if it helps
I'm trying to configure RHive in the CDH4 environment.
When reading a package 'RHive' in R, the error below got returned.
I'm guessing that's due to wrong homes.
If so, what would be the correct ones?
Or if that's not the reason, what's wrong with that?
Any help would be very appreciated.
Thanks.

This is RHive 0.0-7. For overview type '?RHive'.
HIVE_HOME=/etc/hive
[1] "there is no slaves file of HADOOP. so you should pass hosts argument when you call rhive.connect()."
Error : .onLoad failed in loadNamespace() for 'RHive', details:

error: java.lang.ClassNotFoundException
In addition: Warning message:

Error: package/namespace load failed for 'RHive'
Had the problems but solved it. Downside is that I have to keep track of a bunch of sym links
After struggling with install RHive_0.0-7.tar.gz on CDH 4.7.x and getting:
Warning in file(file, "rt") :
cannot open file '/etc/hadoop/conf/slaves': No such file or directory
[1] "there is no slaves file of HADOOP. so you should pass hosts argument when you call rhive.connect()."
In /etc/hadoop/conf
I added a the following sym link ----> ln -s /opt/cloudera/parcels/CDH-4.4.0-1.cdh4.4.0.p0.39/etc/hadoop/conf.empty/slaves slaves
(why Cloudera CHD 4.7 installs in /opt without creating the proper sym links from /usr/lib is puzzling)
I also defined the followingin /usr/lib64/R/etc/Renviron
## set hive paths
HIVE_HOME='/opt/cloudera/parcels/CDH-4.4.0-1.cdh4.4.0.p0.39/lib/hive'
HADOOP_HOME='/opt/cloudera/parcels/CDH-4.4.0-1.cdh4.4.0.p0.39/lib/hadoop'
LD_LIBRARY_PATH='/opt/cloudera/parcels/CDH-4.4.0-1.cdh4.4.0.p0.39/lib/hadoop'
At a shell prompt I ran R CMD INSTALL RHive_0.0-7.tar.gz
Installation Happiness!!

This is RHive 0.0-7. For overview type ‘?RHive’.
HIVE_HOME=/opt/cloudera/parcels/CDH-4.4.0-1.cdh4.4.0.p0.39/lib/hive
call rhive.init() because HIVE_HOME is set.
rhive.init()

You should set the HADOOP_CONF_DIR separately.
Try export $HADOOP_CONF_DIR=/etc/hadoop/conf/conf.pseudo
The conf.pseudo has the slaves file.
Though I'd be curious to see if you can make RHive work with CDH4.
I am trying to run cellcli on my one of the Exadata Cell Server.
When I login to the Server, I am able to see all the files as expected.
(Like: all_group all_nodelist_group cell_group all_ib_group etc)
When I issue command to start cellcli it gives me error that command not found:
# cellcli
-bash: cellcli: command not found
# which cellcli
which: no cellcli in (/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin)
Any idea what is the location of the cellclie executable on exadata?
Do I need to export any other path to get this command?
cellcli is in /opt/oracle/cell/cellsrv/bin. It should be put in path by /etc/profile.d/cell_env.sh
