Thank you Esteban for reply
I tried to do @hbase.hbase_admin but I could not call any methods from
HBaseAdmin,
for example when I do
hbase(main):001:0> @shell.hbase_admin
I got
=> #<Hbase::Admin:0x43fda8d9
@conf=#<Java::OrgApacheHadoopConf::Configuration:0x7318daf8>,
@formatter=#<Shell::Formatter::Console:0x600f5704 @out=Kernel,
@max_width=236, @row_count=0>,
@admin=#<Java::OrgApacheHadoopHbaseClient::HBaseAdmin:0x2503ec73>>
but
@shell.hbase_admin.listTables
NoMethodError: undefined method `listTables' for #<Hbase::Admin:0x79b2852b>
or
@shell.hbase_admin.getTableRegions('t')
NoMethodError: undefined method `getTableRegions' for
#<Hbase::Admin:0x79b2852b>
shell is more or interactive tool from what I see but as I mentioned I want
to use it in a scripts for our schema updates
starting with checking for table exist. than need to check regions and
create new base on some conditions etc...
How I can get to full admin/table class in the shell without duplicating
all code in my scripts? I am very new to JRuby and I looks like I just
missing something here...
thank you,
