To resolve this issue, I needed to modify /etc/httpd/conf.d/autoindex.conf, /etc/httpd/conf.d/userdir.conf , and /etc/httpd/conf/httpd.conf.

Find where there is Indexes as part of the directory Options like

Options MultiViews Indexes SymLinksIfOwnerMatch IncludesNoExec

delete the word Indexes from all the options.

Call the code like this

THEANO_FLAGS='floatX=float32' python xxx.py

Cause by a depreciation in numpy 12.x.x. Install numpy 11.x.x or add .astype(np.int) to the part causing the error.

pip install -U numpy==1.11.0.

Happens when working with csv with large cell text. From a stackoverflow question, I found a solution ( to set

csv.field_size_limit to maxInt

maxInt = sys.maxsize
decrement = True

while decrement:
    # decrease the maxInt value by factor 10
    # as long as the OverflowError occurs.

    decrement = False
    try:
        csv.field_size_limit(maxInt)
    except OverflowError:
        maxInt = int(maxInt/10)
        decrement = True

This Solution tries to avoid the overflow error.

Edit the /etc/logstash/logstash.jvm add or edit the lines

-Xms4g
-Xmx4g

set the size of memory you want. Here I used 4GB

set the correct permissions to the new data and log directories (i.e) set elasticsearch as the owner of these directories

sudo chown -R elasticsearch  /path/to/directory

copy table_name(column1, column2) to '/path/to/file.csv' delimiter E'\t' csv header;

grep -rnw '/path/to/folder/' -e "search string"

For example to extract from line 20397949 to line 20406761. The lines are extracted from extract_from_file and written to extract_to_file

sed -n 20397949,20406761p extract_from_file > extract_to_file

grep -nr search_text File_name
